It's very very simple on the inside:
- TQFP-48 sandpapered so I can't read the model.
- 8 MHz XT
- 74HC244 octal buffer
- AMS1117 3.3V LDO regulator
- 2x LED
- Resistors and capacitors.
That's all!
I'm not aware of the source being released...

Ok, so this means it is not an FTDI FT245 + MAX CPLD (USB-Blaster), and the Cypress FX2 EZ-USB
http://www.cypress.com/?docid=34060 doesn't come in a TQFP-48.
Given the fact that they use ARM in the name, I'd guess it was a USB ARM microcontroller, eg., an NXP LPC2000 series device.
Is there another header on the board for programming the TQFP-48 device? If there was a JTAG header there, you could read the JTAG IDCODE and figure out what the device is. The LPC2000 devices can also use serial ISP for programming, so the header might not be JTAG.
But this doesn't help you solve your original problem with Linux ... :)
