USB -> CDC-ACM with TI eZ430u

OMAP3 · 04-15-2009, 02:54 AM

Hello all,

I am actually trying to setup the linux cdc-acm driver for my eZ430 dongle. It contains a TUSB3410, with a CDC-ACM built-in firmware, so, to recognize it, I have to use the USB CDC-ACM driver.

The firmware of the TUSB3410 is kinda wrapped, since it only exports 1 interface ( COMM ) whereas the CDC-ACM specs tells we need 2 interfaces : a COMM and a DATA.

Windows CDC-ACM driver seems to support this kind of "reduced CDC-ACM", but Linux's one doesnt ...

Does anyone has already seen this issue ?
How to solve it ?

Actually I managed to get TX working (USB to serial), but RX (serial to USB) doesn't work.

Thanks for your help.

Can you post the output of 'lsusb' and 'dmesg | grep -i usb' ?

Thanks for your help hurry, but I finally managed to hack the Linux CDC-ACM Driver to make the TI eZ430u work.

I won't share it since I didn't hack it in a clean way, except if anyone really wants the patch.
