Comment 12 for bug 565613

Hi Grant,

Based on dmesg, the chipset in my Linksys WUSB54G is an Intersil Prism 54. The p54 driver loads when I plug in the adpater. This could be erroneous; I believe I've seen Linux in the past load a compatible driver with certain devices when the actual driver wasn't available.

Hello Carlos.  How "fresh" was your first fresh installation?  If it was
an upgrade from Karmic it could have been using the Karmic drivers which
Adrien reports worked very well.  It your experience truly did show that
it worked from the installation kernel and failed with the installed
kernel that might be an important clue in narrowing down this bug.

I sometimes have troubles with wifi of my own hardware and others who I
help at user groups from time to time so I know how frustrating it can
be to see it work with Windows and not work with Linux.  This is one of
those nasty cases that can use all the help it can get so a fix can be
found for all possible cases of slightly different hardware.

I talked to Adrien Lamothe on Sunday at a LUG meeting.  I insisted we
try plugging his USB adapter into my Lucid laptop running linux-
image-2.6.32-23-generic (2.6.32-23.37) kernel that has the linux-
firmware-nonfree 1.8 installed on it already.  It failed to recognize or
show up with sudo lsusb -v for some reason.  My guess is this was due to
several suspend and resume events.  I have no problems with other USB
devices on this laptop but without the hardware here I can't
troubleshoot further.

http://en.wikipedia.org/wiki/Linksys says that only v.4 WUSB54G adapters
use the Ralink 2500 chipset.  As I recall Adrien said his uses a
different one.  I hope he responds with more details about how it
appears to the kernel under 9.10.  I believe the WUSB54G is a widely
sold Linksys adapter "model" that has been manufactured using several
different chipsets over time, each needing different firmware.  When
looking closely at Adrien's this weekend we found no minor revision
number on the hardware.  Serial numbers might be needed to help track
down this bug if linux-firmware-nonfree still doesn't fix it in all
cases.  Since Adrien has now downgraded back to 9.10 in part because of
this 10.04 bug it would be helpful if other people can take the time to
provide the details that Brian and Jeremy need to help isolate this bug.
