When I connect my Arduino Mini to my TS-7500 board running Debian (Linux ts7500 2.6.24.4), it doesn't show up as a ACM port.

dmesg gives the following output

[14090.3000] usb 2-1: new full speed USB device using str8100-ohci and address 6 [14090.4900] usb 2-1: configuration #1 chosen from 1 choice

I have read here that I have to recompile the kernel. If so suggest some links, or else how do I tackle this problem ?

EDIT : After running modprobe cdc_acm, dmesg shows the following output,

usbcore: registered new interface driver cdc_acm
cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters

but still doesn't assign any port (for eg. ttyACM0) in /dev. What am I missing ?

  • @Flimzy, my question is how to make ACM ports detectable on TS-7500 board. If I have to recompile kernel, yes, I was asking for some links. Else, if there was another way to tackle the problem, do share the same. – Bhanu Kiran Jan 02 '13 at 13:13

Try to modprobe ehci-hcd or ohci-hcd and uhci-hcd. You have to make sure, that support for those USB features is compiled in kernel.

How to compile kernel is described here TS-7500 Kernel_Compile_Guide. It's working well.
