USB: fix SB700 usb subsystem hang bug
This patch is required for AMD SB700 south bridge revision A12 and A13 to avoid
USB subsystem hang symptom. The USB subsystem hang symptom is observed when the
system has multiple USB devices connected to it. In some cases a USB hub may be
required to observe this symptom.
This patch works around the problem by correcting the internal register setting
that will help by changing the behavior of the internal logic to avoid the
USB subsystem hang issue. The change in the behavior of the logic does not
impact the normal operation of the USB subsystem.

Comment #24 From Roman Mamedov 2008-11-21 13:45:53 and patch file attached to the kernel.org bug.
It seems I am experiencing the similar bug: A USB Flash drive inserted into a hub connected to the M3A Asus motherboard(SB600) is being reset sometimes. And some files written to the drive become corrupted. kernel 2.6.27.15-170.2.24.fc10.x86_64 lsusb Bus 001 Device 010: ID 058f:6387 Alcor Micro Corp.

As for the flash drive issue, did you try it on another computer? Does it work fine when plugged directly into the motherboard?

May be this is not exactly the same problem, but I think it's a similar one. As it is also related to SB600 USB. Should I re-file this as a separate issue then? > > As for the flash drive issue, did you try it on another computer? Does it work > fine when plugged directly into the motherboard? Yes, the flash drive works fine on another computer with the same USB hub. In addition, the flash drive seems to work fine also when plugged right into the M3A motherboard without a hub in the middle. So, it's just a duff hub. Nothing to do with this bug, like Roman said. (In reply to comment #7) > So, it's just a duff hub. Nothing to do with this bug, like Roman said. Looks like you are right: I've obtained a hub of another brand and the flash drive works through it. So, the problem is in my hub. Thanks.
