External monitor freezes

joao_r_oliveira · 04-06-2010, 11:20 AM

Hi,

First, sorry for my bad english

I purchase the toshiba dynadock v10 to link all my external devices to my laptop DELL inspiron, via a single USB cable.

All devices (ethernet, mouse, keyboard, external hard-disk) work well, except the TFT samsung (conected via DVI-I to VGA adapter), that after a while of work well, freeze

and i have to use the laptop monitor instead.

This TFT is working OK, when disconected from the dynadock.

I´ve instaled the new 5.2 version and even the beta 5.3 version, but the problem is still existing.

Do you have similar problems reported ? what is the solution ?

thank´s

Hi

This could be caused by errors on the USB bus. Corrupted packets are causing the video on the dock to lock up. Could you try a different USB port or a different USB cable?

Thanks

Wim

Hi

Thanks for the logs. They show:

01:04:22.440 DeviceWindow:USB_0117_002780 DeviceRaw USB_0117_002780 WARN DeviceRaw.cpp:133 Connect USB_0117-002780 failed: USB transmit failed

This means that there is a communication problem on USB and the software is losing connection with the dock. My guess is there is a hardware fault somewhere in the connection from the USB dock to the PC. I'm pretty sure its not a software issue.

I'm also seeing this issue the 5.3 beta drivers.

My setup is a HP 2710P tablet running Windows 7 x64.

When this issue happens (usually on or two times per day) pressing winkey + p and switching from display mode from "Extended" to something else and then switching back brings the displaylink monitor back to life again.

I never had this issue with the 5.2 driver.
