I don't think Uros is on the list as I believe he moved on to other
endeavors quite a while ago.

I'm the current maintainer.

I've had good results with the stk200/300 dongles with linux. Are you
using direct IO or the parport driver?

Also, which version of uisp are you using?

That doesn't sound like much fun.

The ATAVRISP is basically a stripped down version of the stk500. It
can only do ISP programming via the SPI interface. It should support
those devices fine with UISP (take that with a grain of salt since
I've never used the ATAVRISP).

I'd recommend just spending a tad more and getting the stk500. You get
quite a bit more functionality including HiV programming, support for
more devices, LED outputs and Switches for input during prototyping,
