>Description:
During booting, or when plugging in different USB devices after unplugging
them, I get the following errors:
uhub0: port 1, set config at addr 2 failed
uhub0: device problem (SHORT_XFER), disabling port 1
uhub0: device problem (SHORT_XFER), disabling port 2
The kernel output before this suggests that it has detected my usb hub and
plugged in devices correctly. Running usbdevs after bootup gives an error
message:
addr 0: (this shouldn't happen)
(or something like that). If I leave the computer for a small while (1-2 min),
I get error messages similar to the above, but with SET_ADDR_FAILED in
parenthesis. I can unplug devices and put them somewhere else, but I get the
SET_ADDR_FAILED error messages with FreeBSD reporting that it has disabled the
corresponding port, rendering the device unusable or undetectable. This
prevents me from using my USB Ethernet modem (Motorola SB5100), which otherwise
ends up with a device node (/dev/net/cdce0). Disabling and enabling ACPI seems
to make no difference (same error messages).
I am using a Gigabyte GA-7DX+ motherboard, latest BIOS update. It has a VIA
686B south-bridge chipset, and a AMD 761 chipset. I'm thinking that the drivers
are not giving enough time to the usb bus to send data back. The hardware works
correctly and without errors in Windows 2000, and works with Linux kernel
version 2.6.14, with the irqpoll option on (without this, the Linux usb stack
would crash, reporting an irq conflict, which I think I solved by moving by
SBLive5.1 card).
>How-To-Repeat:
Hardware:
Gigabyte GA-7DX+ motherboard (AMD 761 chipset, VIA 686B south-bridge)
AMD Athlon XP 2000+
2 usb ports with following layout:
port 0: nothing
port 1: generic usb hub with 4 ports
port 1a: brother hl2040 printer
port 1b: Motorola Surfboard SB5100 modem
port 1c,1d: nothing
try bootup with devices plugged in.
