Hi,
I'm trying to get USB bluetooth dongle to work on a toshiba P133
laptop (usb-ohci.) Bluetooth communications ('pan') work for a short
time. The dongle is unresponsive until re-inserted. This often
results in an oops.
I ran such an oops trough ksymoops. I gather the lud-list would be
interested. Of course I hope there's light at the end of the tunnel.
So here goes:
/proc/bus/usb/devices says:
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2
B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0
D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=0000 ProdID=0000 Rev= 0.00

E: Ad=81(I) Atr=03(Int.) MxPS= 2 Ivl=255ms
ksymsoops results in:

Hope you all don't mind this long e-mail. I'm off now, to try 2.6.0-
test1.
