USB Serial support for stk500v2

I have a board the stk500v2 protocol over USB serial. It’s worked on every Linux distro I’ve worked with out of the box. Is there any chance that that protocol is not supported by the kernel?

I read several instructions saying that FTDI modules needed to be installed into the Kernel, but more recent versions had it built in.

I guess for Kernel it’s not turned on:

zcat /proc/config.gz | grep FTDI

CONFIG_USB_SERIAL_FTDI_SIO is not set

CONFIG_USB_FTDI_ELAN is not

I see an application available via apt-get, “uisp”. Is this the application you are using? I don’t know about the stk500v2 protocol, but it does look like it is a feature in kernel configs, so if “lsusb” recognizes the device, I would think that uisp would work when the kernel has that configured.

CONFIG_USB_SERIAL_FTDI_SIO is found in:
Device Drivers .> USB support -> USB Serial Converter support
…prompt USB FTDI Single Port Serial Driver.

CONFIG_USB_FTDI_ELAN is found in:
Device Drivers -> USB support
…prompt Elan PCMCIA CardBus Adapter USB Client

If you use “make nconfig” in the kernel compile it has a symbol search function which is useful. Whether those are indeed the particular configurations you need I don’t know, but it isn’t too hard to test.
