I've done some tests with several USB hubs, but same results...
Now I've got an official Altera USB Blaster and "sudo lsusb -v -d 09fb:6001" shows exactly the same that DE2.
I think I'll contact my clone vendors to ask them to check/correct this. The only difference shown in lsusb between the clone and the original is:
bMaxPacketSize0: 8 (altera) vs 64 (clone)
iProduct and iInterface: USB-Blaster (altera) vs USB-Blaster-ARM???? (clone)
iSerial: 91d28408 (altera) vs 8D8C41695350 (clone)
bMaxPacketSize0 might make the difference. Do you think that iProduct, iInterface or iSerial might have any influence?
Do you want me to go on revere-engineering my clone?
Thanks a lot!

Wow, I'm having the same problem as you.. on Win8 it runs fine, on Linux.. It doesn't. It recognizes my cable, I'm able to run once jtagconfig, then it doesn't work anymore and I have to remove and insert back the cable. I'm able to program my device, but to call a tcl with Signal trap doesn't work.. please can we try to reverse engineer it?
the output from my dmesg:
[20062.358849] usb 3-2: new full-speed USB device number 8 using xhci_hcd
[20062.370796] usb 3-2: New USB device found, idVendor=09fb, idProduct=6001

[20062.370821] usb 3-2: SerialNumber: 8D77536E5655
it is a sainsmart, rev.C, like the one listed on their website. from the spec you can read something like:
- ALTERA USB ByteBlaster
- USB interface
- FPGA/CPLD download
- SignalTap II embeded logic analyzer
- NIOS II debug
Any difference between Blaster I and ByteBlaster?
