Linux is unable to correctly use the right device driver for my
JumpDrive trio: It detects it as a high-speed device, but the EHCI
drivers error out when it is plugged in, the UHCI driver can handle it
(although Linux complains "not running at top speed; connect to a high
speed hub". If the UCHI driver is not loaded, then NOTHING happens when
the device is plugged in.
Without USB debugging, Linux doesn't really say why it wont work. With
debugging, though, it spits out a lot more informative information
(with nothing plugged into any of the USB ports):
ehci_hcd 0000:00:10.3: GetStatus port 1 status 001030 POWER sig=se0 OCC OC

ehci_hcd 0000:00:10.3: GetStatus port 6 status 001030 POWER sig=se0 OCC OC
hub 1-0:1.0: over-current change on port 6
The "over current" stuff is completely implausible: Nothing is attached
to any of the USB connections, and 2 of 6 ports are on the motherboard
but currently have no USB ports connected to them.
When the device is plugged in, the following errors get spit out:

The machine is question is one I built myself. Neither "acpi=off" nor
"noapic" fixes the problem. I'm not sure if the problem the flaky
hardware or if its a driver bug. The device works fine in full-speed
mode (at 12MB/s, of course). This is the only high-speed device I have,
all my other computers only have USB 1.1 ports and all other usb devices
are USB 1.1. Its never worked right as far as I know, tested it on a
kernel as early as vanilla 2.6.8.1 and as late as 2.6.15-rc2-git6.
Current kernel is 2.6.14-gentoo-r2.
I'm stumped on this one, any clue what's going on?
