Is it actually running in isochronous mode? (It prints some messages
about this). You may need new firmware (I've attached some recent
firmware that was made available by Thomson UK without any licence
conditions).
Unfortunatelly this firmware does not work with my modem. I get this
thing in the debug log:
Jul 10 09:26:27 srv kernel: speedtch 1-2:1.0: speedtch_upload_firmware entered
Jul 10 09:26:27 srv kernel: speedtch 1-2:1.0:
speedtch_upload_firmware: BLOCK1 uploaded (935 bytes)
Jul 10 09:26:29 srv kernel: usb 1-2: speedtch timed out on ep5in len=0/512
And it hangs at this point for a couple of minutes, so I have to
manually remove the speedtch module. As far as I can see my modem is
revision 2.00 (kernel searches for firmware speedtch-1.bin.2.00).
I also tried a couple of other firmwares available on the net, and
also the one from Windows XP install (which works and achieves speeds
of up to 720kbyte/sec downlink). Some of the firmwares did not work
either, and some worked the same way - it means not more than 3mbit/s
(around 400kbyte/s) could be achieved.
