Problems using external USB hub with A30

I have a Toshiba Satellite A30-514 with a USB powered 2.0 hub attached. In it's plugged a powered satellite Receiver/USB modem (for connection broadband), a USB bluetooth adapter and a HP PSC 1350 printer. The first two devices work fine, but the printer is not recognized correctly.

The powered USB hub is plugged into the first USB port on the laptop. The second USB port on the laptop is used by the receiver for a wireless optical mouse. It must be here otherwise, it does not work.
If I plug the printer directly into the second USB port on the laptop, it works fine.

In Device Manager, instead of show all HP devices it comes to peripheral USB Composite in the USB controllers section. It is an orange exclamation next to him.

If I boot the laptop with all 3 devices plugged into the hub and turned on, the printer is detected fine but the Bluetooth Radio devices have an orange instead exclamation point. I need the bluetooth device to attach a cell phone to the laptop. If I unplug the printer and restart the bluetooth is detected OK. Plug the printer in causes the Composite device to reappear with the exclamation point!

From left to right, looking at the front of the hub, devices are 1) satellite receiver/modem, 2) Bluetooth printer) 3.

I hope it's clear. Any help / advice would be received with gratitude.

Hello

I think the problem is that one of the devices does not have enough power to operate. This is because a single USB port must provide 3 devices with power. If you have an external power supply to one of the features of this you should use.

Good bye

  • Toshiba 39L 3300 problems using external USB WLan WLM-20U2

    Hello

    Recently, I brought a 39L 3300 smart TV toshiba and got a free dongle for internet connection.

    However, I was unable to connect to internet via wifi. The dongle I got from the Bank is a Toshiba dual band wireless LAN adapter WLM-model 20U2. But it doesn't seem to work at all when connected to the USB port. I checked with the other connectors USB port to watch movies and it works well.

    The choice of type of network does not appear after the dongle is connected. Could there be a problem with this model of dongle? The user manual specifies a Toshiba dual band wireless LAN adapter WLM - 40U model. But the store gave her.

    No matter which also I have this problem, please help.

  • Satellite M300: speech recognition only works with external usb hub

    Hi all

    I have the Satellite M300 I could run the speech recognition program before you have the motherboard replaced due to failure of the usb.

    I found using the headset, I can not reach high enough quality to operate it.
    The only way I can use the Word program, use an external usb hub with its own power supply.

    The problem concerns the audio card, or simply not enough voltage?
    And na fix?

    See you soon

    Hello

    The notebooks of USB ports provide a standard power of 500 my.
    As I said that it is a standard, but in USB devices different part 3 external cases need more power.

    For example, one of my external USB 2.5 HDD s must be connected with two USB ports at the same time to ensure that the HARD disk would get enough power to function properly.

    Your external card is unknown to me but maybe it needs more power as usual.

  • IBM travelstar external USB compatibility with Portege 3480CT

    Hello
    I try to use an IBM & reg travelstar in a box external usb with my Portege 3480CT running Windows 2000 (with sp4). While the disc is recognized as plug-and-play on other computers running win2k and winXP, is not recognized on my Portege, which gives an error message suggests that the drivers are missing.

    According to IBM/hitachi (which make the player), no drivers are needed and the drive should work as plug-and-play, recognized as a generic USB HDD. This happens all other computers I've tried.

    Are their compatibility problems with this drive? Or are their special all the drivers necessary to recognize this configuration on the Portege?
    Thank you
    B

    Hello

    AFAIK there is no driver required for external hard drives and they are recognized as plug-and-play. Your Portege is an old unit and there may be a problem with the USB ports. Have you checked the other USB devices?

    It is also possible that there is not enough power, and in this case, it is recommended to connect the drive using USB hub with own power supply.

    Hello

    The player and the hub are not compatible I've seen. Maybe try a different HUB.
    (Is the HUB you use powered, otherwise this could also be a possible cause of wiring).

    I hope this helps.

  • Connection USB Hub with Multiple Hard Drives Wi - Fi router

    I was shopping for a router wireless n. I liked this one because of the Gigabit and the usb socket: http://www.linksysbycisco.com/CA/en/products/WRT610N

    I was wondering if I could plug more than 1 hard drive into this USB port using a usb hub. I would like to use the router as a kind of SIN. I have a few drives hard usb and I would like to access it without having to be on all computers.

    Don't you think that the firmware on the router supports more than 1 hard drive? Has anyone tried this before? Can someone test it for me if you have the right hardware?

    No, the Linksys WRT610N, you can use a single USB and hard drive... However on NAS200, you can use two USB and two hard drives.

  • Problems when I want to update my complete system Mavericks using a USB key with the installation program.

    I want to "Refresh" my Mavericks home cleaning system and I still have a USB key with the complete installation program.

    With this USB key, I installed successfully already before Mavericks. Now, I want to repeat the installation by booting from USB key. But when the installation starts early an alert appears, said something like "... the verification failed - something is changed on the volume...". "and the cant of the installation continues.

    I've archived the original "OS X Mavericks installieren.app" from the app store and I have properly prepared another USB key using the terminal app, referencing the original installer, but I still get this alert when I try to install with this new USB.

    It is necessary for me to work with the Mavericks, because it's the latest version of the system on which I can run Adobe Creative Suite CS6 correctly. With the later versions of OS X, I get problems on my Mac Pro (end of 2008).

    I wonder what could happen with my first USB data, as I have already installed Mavericks successfully with it under the same conditions and after that he never touched the stick again so far. What can I do? What is the reason for this? Y at - there a site where I can get help or advice to solve the problem or if necessary can I re-download an Installer 'fresh '?

    Thank you and what is Berlin

    You can make a bootable USB to install using this free program that will do all the work for you. Try running disk utility/repair disk be before installation.

  • Satellite A200: Cannot properly use external USB devices

    I encountered a problem with my Toshiba laptop and I can't fix it, and I'm in need your help please...
    The problem is that when I connect a USB portable device (an external hard drive, USB, iPod, Flash memory... etc) with more than 8 GB of memory...
    It is not properly installed in the Device Manager and appears under "USB bus controllers.

    But it does not say that it is an unknown device. It normally appears with his name, but he is not properly installed (it does not say that either) where it is supposed to be a camera under "imaging devices" in a specific category (hard drive under "drives"), and so on

    And I can't use the unit because the HARD disk does not appear in 'My computer' and my iPod cannot be used

    I would like to inform you that this problem is with all USB devices with more than 8 GB of memory.
    Not a single device. I tried a lot of features to ensure that it is not a problem with the unit.

    So this is a problem with my laptop and I installed Windows several times but no progress.
    Thanks for your help in advance...

    If its XP, make sure you have at least Service Pack 2.

  • External USB hub limit for Satellite Pro C650

    Is there a limit to how much you can connect via the Satellite Pro C650 of external usb ports?

    Provides four ports hub I, ports seem to work individually and all devices operate normally when plugged directly into the top of the Tower, but when all devices are plugged into the hub and combined high tower, there are future errors.

    Thank you
    Karyn

    Well, I think that this should not be a problem if the unique USB hubs provide clean power.
    The fact is that the only USB port provides common 500mA and if several devices would share the power of a USB port then it might be possible that the 500mA available would not be sufficient for all USB devices.

  • Trouble using NI USB-4065 with virtual machine VMWare

    Hello

    I'll be working with a virtual machine (windows xp) and I need to use an NI USB-4065 DMM.

    When I connect the USB-4065 to the PC, the virtual windows xp recognizes the new HW and also MAX display the new device on the list DAQmx.

    It seems ok, but if I try to use the USB-4065 (open the soft cover or in a LabView VI), the device does not work.

    If I use the frontpanel app, when I click a botton, the Group seems to work but doesn't measure anything; If I try to reboot the softpanel, it works and 'freeze' of the screen.

    If I use LabView, the VI returns an error on a maximum duration of the measure.

    I'm trying to use the device on the real machine (not with VMware) USB-4065 works, whith flexible Panel and whith VI.

    I update the driver of the DMM on the virtual machine, beats the device still doesn't work.

    ... I don't have any other idea, can anyone help me with this problem?

    Thanks, SEM.

  • Can I use a USB hub to connect to more of a GPIB-USB-HS USB ports?

  • using NI USB 9201 with LabVIEW Real-time

    Hello

    I try to use a USB of NI 9201 on a remote real-time target. Here's what I did: 1) tricked out of a desktop PC to serve as target RT using the instructions provided on the Web site of NOR. He now starts in an RTOS with LabView RTOS 9.0. (2) I communicated successfully with the help of a host computer that has a windows with LabView 2009 BONE and I installed the software from the computer remote RT target host using ethernet. However, my problem is when I plug NI 9201 USB on the target RT that I do not see the material listed on the devices tab in MAX and interfaces on remote systems. I tried to get the manuals for the HW 9201, but it seems not much explained here, or maybe I'm looking in the wrong places. Any help is greatly appreciated.

    PS: I am attaching 2 JPEGs for additional explanations (tab network settings and the settings of the system).

    Thanks in advance,

    Benoit.
