KM266/VT8235, USB2.0 and problems
From: lk
Date: Mon Jan 05 2004 - 00:33:30 EST
Hi. I've noticed that intermittently in the past with some devices, and
now every time with my new USB2.0 thumb drive (aka pen drive, aka flash
memory thing) that there are errors with the USB on my motherboard. It's
a M7VIG-PRO, which has a KM266/VT8235 chipset.
Using kernel 2.6.0, I can only access my flash drive several times before
getting an error about not being able to access the device. The dmesg
output is below. When I try on my laptop, which has an EHCI USB2.0
controller, the device works flawlessly. There are no errors, etc.
I am using a USB keyboard and a USB mouse. Both work fine.
I've tried several combinations of connecting the device, with and without
the "noapic" kernel option while booting. I've connected the device to
the motherboard's USB sockets (ie the ones soldered to the board, not via
wires to the case), through a USB2.0 hub, etc. I get the same result
every time.
I've included the relevant parts of "dmesg" and "dmidecode". Please cc:
me on responses, since I'm not subscribed, and let me know what to try
next.
Thanks.
