Just in case it matters any, here's the Clie (760C) part of my
/proc/bus/usb/devices:
T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=ff(vend.) Sub=00 Prot=00 MxPS=16 #Cfgs= 1
P: Vendor=054c ProdID=0066 Rev= 1.00
S: Manufacturer=Sony Corp.
S: Product=Palm Handheld
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=serial
E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
I'll also be a test monkey for the patch.
