hardware connection problem

recently, I connect a lenovo usb dvd player portable for my macbook pro, but most of the time when I'm working on this portable dvd player usb unplug my macbook!

I don't know what the problem is please help me solve this problem! Thanks in advance

The question is usually the Bus power issues, and for DVD players, it's a BIG problem. Sleep and wake in general strike these devices offline until you restart.

If there is a way you can provide a power supply for this unit, it will be much more reliable.

  • Satellite L10-119: OKI 8w Lite printer connection problem

    I have the Toshiba Satellite L10-119 series. I use it with 8W OKI printer. The printer works on USB port. Every day, when I print a ~ 10 pages of the judgment of the printer and XP driver display statement "connection problem". Currently, OKI prints all pages. Only restart helps XP on.

    The operating system is Windows XP and printer has an OKI dedicated for XP drivers. Other USB devices are working properly. I reinstall the Intel chipset drivers, I checked the printer on the other ports.

    Please send a sollution mail: michaljaniszek (at) walla (dot) com

    Hello

    You suggested that all other USB devices work properly on this unit.
    In this case, I guess that it s not a Satellite L10 problem but the OKI printer problem.
    Unfortunately, Toshiba is not responsible for the 3rd party hardware or software.

    However, I studied a bit on the net and found a few questions about the OKI printer problems. There are different issues and all have suggested contacting the OKI support. Well, in my opinion you should also ask the support. There may be more recent driver. Check it out.

    Good luck

  • Network host connectivity problem

    Hi all
    I have a bit of a strange an ESXi 5 U1 host connectivity problem. The host has a network card in the 10.0.0.0/24 subnet, and from there it can ping both devices but cannot ping to two other devices. To explain a little better:
    There are two hosts with identical hardware (HP ProLiant DL380 G6) both built with the same picture of ESXi 5 U1 from HP.
    There is an IP address on the switch (Cisco 3750 gigabit) management.
    There are two servers running Openfiler, which I'll use for ISCSI data banks.
    All these devices are in the same VLAN in the 10.0.0.0/24 subnet. host 1 is identical to the 2 host configuration (bar IP address and host name, etc.). Host can ping all devices on the subnet 1 and maybe ping by all devices on the seubnet. 2, the one with the issue of the host can ping and ping the Cisco FoxyCode and host 1, but cannot ping or ping by one of the two boxes openfiler.
    Research on the openfiler boxes I see missing entries in the arp (marked as incomplete) table. Host 2 he entered complete arp for the openfiler boxes. A trace of the wireshark package shows the openfilers sending arp requests but no response from host 2. The Cisco and host 1 to get the answers.
    I have patched the critical fixes host 2 until the last critical and no, applied the latest versions of firmware HP etc. Swapped, cables, tried different switch ports and even different NICs on host 2, all to nothing does not. The Cisco ports configured all identically from host 1. The openfiler boxes are set up with interfaces servile and the Cisco switch ports are etherchannelled for these. There is no etherchannel or link aggregation etc for guests, straight connection to the front in the VLAN.
    Interestingly, all devices also has an interface in the 192.168.2.0/sous-reseau 24 for management and all devices can see all other devices here absolutely fine.
    If anyone has any ideas on where to go from here please let me know, I'm going crazy trying to understand this one!

    I wonder if the Etherchannels in Openfiler servers might not work. Depending on how the switch load balances executives, this could cause a host to work and the other is not.

The same thing happened yesterday with the updates listed on the tab Update on the app store - they have been is downloaded yesterday without asking my login details but it was a rare event; connection problems I described above took place during the last month or so.

I get a message that the network could not be attached (I ran the Diagnostics wireless, but it's a whole lot of sense to me empty files). However, I also have a Roku, and which IS connected to the WiFi without problem. I completely stopped and restarted the computer, no joy. Reset the modem and the router, no joy. Still works with Roku, not with the computer. But the weird part is, I have Optimum Online, which allows subscribers to log-in to its hotspots, and it worked! I am connected Optimum wi - fi network on my computer right now.

    So I don't know where is the problem! It is not the router, because this is related work with Roku and is not the computer, because it is connected and working with the Optimum hotspot. What gives?

    Try this!

    Go to the Apple menu > System Preferences > network

    Select a Wi - Fi connection in the sidebar and then click on the button "Advanced...". "in the lower right corner of the screen

    In the list of preferred networks, delete the name of your Wi - Fi network
