[Mspgcc-users] USB FET tool support

[Steve Underwood]

Hi,

Are there any USB experts out there who would be willing to help get USB 
FET tool support working with Linux?

The standard Linux distribution includes a driver for the TUSB3410 USB 
chip used in the TI USB FET tool. However,this driver is only designed 
for the generic use of the TUSB3410 chip as a USB to serial interface.

In the FET tool the USB chip has been given a unique USB ID. This is no 
problem, as additional IDs can be added from the command line of the 
existing Linux driver.

In the FET tool the USB chip has two endpoints, while as a generic USB 
to serial interface it has only one. This is more of a problem, as I am 
not a USB expert, and I don't know how to handle these things. The 
current Linux TUSB3410 driver won't even load firmware into the device.

It feels like it should not be a big problem to adapt the current Linux 
driver, to make a FET tool driver. However, learning enough about USB to 
make this work nicely will probably take me a while. Is there anyone 
around prepared to help shortcut that?

Once a driver is available allowing communication between the 
application and the FET tool, the rest should be easy. There appear no 
significant hurdles to getting the existing Windows USB FET tool 
software to work after communication is established.

Regards,
Steve
