Presumably the two messages indicating a 480 Mb/s connection came before the port was reset and hence before the actual speed was known. > cat /proc/bus/usb/devices: > > T: Bus=03 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 3 > B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 > D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 > P: Vendor=0000 ProdID=0000 Rev= 2.06 > S: Manufacturer=Linux 2.6.15 ohci_hcd > S: Product=OHCI Host Controller > S: SerialNumber=0000:00:03.1 > C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 0mA > I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub > E: Ad=81(I) Atr=03(Int.)

I have no idea what's going on with Windows, but the indication here is that the stick really is a USB 1.1 device, not USB 2.0. That's what the "Ver=" field in /proc/bus/usb/devices shows. What does "lsusb -v -d1043:" have to say about the stick? Alan Stern ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
