hi,
i have a type of usb-stick that works fine under older kernels (tested on
2.6.34 and 2.6.37) but stopped working for 3.0 and 3.1
this is a working insert:
[ 2983.692212] usb 1-5.1.1.4: new high speed USB device using ehci_hcd and

but it seems that the reading of new sticks got a little stricter and now
under 3.0 and 3.1 it looks like this:

the detection and changing of capacity to 0 repeats over and over.
i have two sticks of the same type and they both show this behaviour.
when i lsusb -v it (see attachments), changing timeouts when reading
drescriptors/qualifiers happen on both kernel versions. (i tried multiple
sticks on multiple kernels and systems).
so there seems to be something wrong/different with the type of stick to
begin with, as it seems to be slow in answering to the requests sent by
lsusb. but apart from the timeouts on lsusb, the stick works fine under
older kernels.
in of of the lsusb outputs, it hangs for 1-2 seconds before outputting
anything and the output ends in:
Usage Type Data
wMaxPacketSize 0x0040 1x 64 bytes
bInterval 8
bInterval 8
can't get device qualifier: Connection timed out
can't get debug descriptor: Connection timed out
cannot read device status, Connection timed out (110)
it looks like initialization got a little stricter in recent kernels and now
the kernel rejects this stick.
is this the case?
does my interpretation make sense?
if yes, are there any settings that control timeouts/retries that i could
change to tune the initialization behaviour?
since the stick works fine on other systems, it would be nice if it worked
under recent linux kernels as well.
i recorded some usbmon logs, if those would help.
i can do more tests with other kernels, but i thought i'd ask what kind of
information would be helpful before i do more debugging.
