BIOS/USB alternative

Kurt Jensen

we are using the c6748 as a USB device. but it is a specialized manufacturer device, not HID and not mass storage.

BIOS/USB works great for HID and MSC but does not allow such a radically difference device (at least that I can decipher so far...)

I have been trying to bring up the USB myself but keep hitting brick walls. right now I can initialize the device, get a reset interrupt, my PC shows something happening in Device Manager, but I never see any kind of enumeration

is there any sample code out there to help me get my USB device off the ground?

Hello Kurt,

Please check StarterWare for C6748. It may solve your problems.

Kurt,

My company has developed a USB Driver that supports the CDC-ACM device type. It allows for bulk transfer of data to and from the C6748, and should not require a custom device development for the host/PC.It is run-time configurable with 1-3 virtual serial ports allowing you to separate you data streams and control schemes and is very simple to use, and can achieve impressive data-rates.

If you want further information please look here:

A demo version is available, and you can get the documentation from our web-site ( the second address ).

Please feel free to email me directly with any questions,

Yours,

Peter
