Well, it's all rather bizarre, but I think I might have located the problem. Ultimately the isoc option doesn't seem to make the difference that I hoped it would. Here's what I got when I first loaded the driver (2.6.15.1, latest CVS, enable_isoc=1). /home/alistair/speedtouch/speedtch.c: speedtch_usb_init: driver version 1.10 usbcore: registered new driver speedtch usb 4-1.4: new full speed USB device using ehci_hcd and address 4 speedtch 4-1.4:1.0: usbatm_usb_probe: trying driver speedtch with vendor=06b9, product=4061, ifnum 0 speedtch 4-1.4:1.0: speedtch_bind entered speedtch 4-1.4:1.0: isoc support enabled speedtch 4-1.4:1.0: speedtch_bind: firmware not loaded usb 4-1.4: reset full speed USB device using ehci_hcd and address 4 speedtch 4-1.4:1.0: usbatm_usb_probe: using 3200 byte buffer for channel 0xd979a2a4 speedtch 4-1.4:1.0: usbatm_usb_probe: using 3392 byte buffer for channel 0xd979a2ec speedtch 4-1.4:1.0: speedtch_find_firmware: looking for speedtch-1.bin.4.00 speedtch 4-1.4:1.0: speedtch_find_firmware: looking for speedtch-1.bin.4 speedtch 4-1.4:1.0: speedtch_find_firmware: looking for speedtch-1.bin speedtch 4-1.4:1.0: found stage 1 firmware speedtch-1.bin speedtch 4-1.4:1.0: speedtch_find_firmware: looking for speedtch-2.bin.4.00 speedtch 4-1.4:1.0: speedtch_find_firmware: looking for speedtch-2.bin.4 speedtch 4-1.4:1.0: speedtch_find_firmware: looking for speedtch-2.bin speedtch 4-1.4:1.0: found stage 2 firmware speedtch-2.bin speedtch 4-1.4:1.0: speedtch_upload_firmware entered speedtch 4-1.4:1.0: speedtch_upload_firmware: BLOCK1 uploaded (935 bytes) speedtch 4-1.4:1.0: speedtch_upload_firmware: BLOCK2 downloaded (511 bytes) speedtch 4-1.4:1.0: speedtch_upload_firmware: BLOCK3 uploaded (775545 bytes) speedtch 4-1.4:1.0: speedtch_upload_firmware: BLOCK4 downloaded (511 bytes) ATM dev 0: speedtch_atm_start entered ATM dev 0: speedtch_start_synchro entered ATM dev 0: speedtch_start_synchro: modem prodded. 2 bytes returned: 00 00 /home/alistair/speedtouch/usbatm.c: usbatm_get_instance ATM dev 0: usbatm_submit_urb: urb 0xde6a1b40 submission failed (-28)!

MxPS= 2 Ivl=255m My bandwidth is still locked to just under 500KB/s (4MBits). So either a) isoc isn't working or b) you need to do more than just switch from bulk to isoc to get 8Mbits from this device. The Windows workaround does not suggest this, but I suppose it is impossible to tell. If it's a useful datapoint, I used to get sporadic errors and the USB LED would flash RED if the bandwidth was held close to 4Mbit for a long period of time. This no longer seems to happen with isoc, suggesting the bandwidth bottleneck has been lifted. However, I do not see the 6.6 megabits I've synced at. -- Cheers, Alistair.
