• USB connection for speakers/conrtols do not work?

  Hello.

  My daughter has a bed that connects to an MP3 player via a USB connection and speakers and play controls on it. SanDisk Sansa clip plus is not working, looks like he's trying to connect to a computer to receive information. Is there something I should do differrently or if this feature is not supported with this MP3 player?

  A bed that connects to an Mp3 player? Cool!.  The Clip + has two modes, the MTP and MSC mode (settings > system settings > USB). If you transfer files under the PSG, the songs will not appear on the computer when you connect in MSC mode and vice versa. Most likely your bed does not recognize MTP peripheral devices. That being said, try transferring music on both msc and mtp and do a test. Try to connect the Sansa to your bed under MSC and MTP.

• 485 USB connection for single device

  Hello

  I need to make a very simple connection, but even if I search in the forums and manuals of days I can not yet understand how do. Maybe someone can help me, it's here:

  I need a «compatible with RS485» actuator control The manufacturer gave me the controller with those pins cable pinout: + 5V, TRx +, TRx - and Signal ground. I also have a schema were I see as the TRx + and TRx - are wired to a SN75176 bus transceiver (lines A and B) so I'm confident that I can connect my brand-new OR USB-485.

  The only problem I have is that I don't know how to build my female! I must not control a single actuator, and the cable is short (no need for endings or anything of that).

  Anyone know how to do it? I feel very stupid with three cables in my hand of the actuator and not knowing how to plug them into the RS485

  Thank you!

  Based on this information, I suggest that you connect the sign to pin 4 and 8 of the USB-RS485 + and -to pin 5 and 9. Connect the 0V to pin 1.

  To make complete (especially if you use a cable of length) you must add an active endpoint on one side (as in your photo) and a cap of passive endpoint of the other side.

  The values in the image are far too high. It should be 2 x 390 and 1 x 150 ohms. The passive endpoint of the other side should be 120 ohms.

• USB connection for USB device failed

  Hello

  I have VMware Workstation 7.2 in Win 7 x 64 OS later.

  I want to use the USB-to-Serial Connector but my host OS cannot recognize the driver. This connector works with Win XP, so I don't think that there is a hardware failure.

  Then I tried running XP machine in VMware workstation, but when I map this USB on XP VM with message

  USB to USB Device "Composite Device" connection failed - driver error.

  Do I need to have a good driver on host to the USB VM card operating system? or the device! mark in the Device Manager in the host OS cannot be mapped to VM? or the USB device must be properly recognized by host operating system, as the device is suitable for USB Serial device not Composite?

  Any solution?

  Thank you

  It is a known problem in workstation 7

  in some cases this can be corrected - in most cases it cannot

  recommended workaround: use Workstation 6.5.5

• USB driver for external hard drive

  Is there a download driver usb as a microsoft? My external USB gives an error message about the dysfunction of the usb driver...

  Is there a download driver usb as a microsoft? My external USB gives an error message about the dysfunction of the usb driver...

  Most likely, it is a misleading message.  Most external hard drives do not require a special USB driver.  But check out the website of the manufacturer of the drive.

  What brand/model of external hard drive?

  The player has a power source or he relies on the USB connection for power supply?

  It worked before?  If so, what happened just before the error started?

  What version of Windows, including the service pack is installed?

  Please post the full error message without paraphrase.

  Have you tried to connect the player to another USB port, preferably one on the back of the case, if the computer is a desktop/Tower computer?

• A9T80A #B1H: USB connection

  Try to buy this printer. However, it is said to use a wireless connection. Can I use USB connection for my desk Top PC doesn't have a wireless setup. But my laptop with Wi - Fi. Can I use this printer setup?

  Hello

  The printer provide wireless capabilities, which means that the pritner can connect wirelessly to your router.

  When the desktop PC is connected to the same wireless with a cable (I guess that it is connected to the internet?), you can install the selectig printer wireless installation... that refer to the connection of printer and not one used by the computer.

  So you can install it with a USB, wireless and USB connection does not come into conflict with each other.

  Hopefully it's clearer now,

• Connection 12 '' Macbook to Thunderbolt display does not work (USB - C for HDMI / Lightning)

  I have connected a retina 12 '' Macbook to a Thunderbolt display via two adapters, and no video is coming through.

  Here is what I use:

  1 USB - C for HDMI: (Apple USB - C to HDMI adapter)

  2 HDMI to Thunderbolt (Monoprice adapter)

  Any ideas what's happening? The Thunderbolt display is without a doubt, since power is to come via USB when I plug my phone directly on the back of the monitor. The Apple adapter works because I could try to connect directly to a LG monitor with HDMI ports.

  The present model 2015 MacBook 12 inch Retina does not support the Apple Thunderbolt display

  what I read.  The other models Apple Cinema can work if they are used with correct adapters

  as other brands. Some adapters support the audio, while others do. Note there is

  limits for the specifications of display supported; This can limit their usefulness if it is not better configured.

  Special adapters and cables can allow to configure some display options for use with the MacBook.

  The graphical support through MacBook, MacBook Air, MacBook Pro varies with the specifications.

  The absence of a Thunderbolt port, use of adapters to provide only what it can bear MacBook 12 plug-in software component.

  and the mini-display port cannot connect or transfer at frequencies Thunderbolt usage views. The

  cure should be taken as built-in support for this; If the adapters could carry signals. A new model

  could understand such an improvement; but there is nothing of this specification in the Apple Store again.

• USB connection does not work on my computer for hdr-cx260v

  It is a question (especially) on and off (sometimes). I have worked with Sony and have sometimes succeeded. With the help of the 'extra' 16 GB card works to connect and load. My problem is when I use the video stored in the internal memory and using the usb connection. If/when I ever actually loading the data from the internal memory (I have actually already loaded most, but not the most recent), I intend in the future to use only the memory card "exernal. My most recent appeal of Sony said I have no help since the camery is 2 years and more - they send me an e-mail to a site that gives instructions, but the instructions don't seem to solve my problem. I don't seem to have any connection problem "devices" of my USB ports.

  When I connect the camcorder usb to my desktop (using different connections of USB drive) pc, my computer does not recognize the fittings of the. When I use another card memory USB for same usb connections, the computer recognizes the drive. There have been a few times when the camcorder has acknowledged the connection of the camcorder (most recently on June 12) - but this does not occur at thie time. If I take the memory card 16 GB additional of the camcorder and connect it to the connection of memory card, the computer has always recognized it.

  My problem is trying to get the video from the cameras internal memory via the USB connection.

  I think if/when can I get these loaded files, I have the intention of is no longer using the internal memory of the camera and always use the extra memory card.

  I realize that if I could have the laptop recognizes the usb connection, I could manually copy video files myself, even if I think THAT TDC would have also worked in this case.

  You should be able to synchronize with a compatible Picture Manager, but you can also see the TouchCopy application.

• my mac is the display of the comment... No backups for 13 days.  Connect to a power outlet while your backup disk is available.

  My Mac is the display of the comment... No backups for 13 days.  Connect to a power outlet while your backup disk is available.  For my time Machine control, everything seems to be saved.

  Time Machine also creates temporary copies on your internal drive when the backup drive is not available. So you can see the 'temporary' backups on your internal drive.

  I recommend that you connect your external drive and your power adapter and let make a permanent copy - ones on your internal drive are subject to deletion if space is short.

  By now he may need to do a 'deep traversal' which can take some time.

• drivers installation for OfficeJet J6450 on Windows 7 (64) and the software doesn't detect USB connection

  I install the drivers for OfficeJet J6450 on Windows 7 (64) and installation software doesn't detect USB connection.  I recently had to upgrade Windows 7 in Place.  The printer was working fine before the upgrade.

  Hi shconner,

  Looks like you need to uninstall what is already installed. Restart the computer and use the software features on the Web site to reinstall the printer.
