Greetings,
I think there's something wrong with the USB bus on my
computer, but I'm looking for a clearer explanation.
The system is a home constructed AMD64 running SuSE
9.2, about a year and a half old. Has never given me a
lick of trouble.
Symptoms:
o One day I rebooted my computer and found that I could
not mount my external 160GB drive. fsck would not do
anything. At first it was giving me a bad superblock
message. Not good, but sometimes symptomatic of less
than the worst possible scenario, namely a disk
crash. Right now fsck says it's not a valid block
device. The node is in fact a block device.
Presumably its not being a "valid" one is determined
by trying to access the physical device and not
finding it.
o I also have a generic card reader on the bus to read
my digital camera's SD cards. The green light doesn't
even come on. I pulled it off and threw it on the
Mac, where it worked fine. This suggests maybe the
external drive is okay, and that there's a bus
problem.
o The external drive is hanging off a port on the back
of the system. (I tried moving it to the second one
with no improvement.) The card reader is off a port
on the front.
o lsusb
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
Looks kinda like nothing's there, eh?
But wait, there's more:
o I have a gizmo on the bus -- a USB powered keyboard
vacuum[1] -- and it gets power and whirs away, doing
what it's supposed to do to the best of its inept
ability when I push the buttons. So at least there's
power coming through.
I'm not sure what to do from here. Suggestions?
Footnotes:
[1] Close to worthless, if you've been considering
buying one.
