Afaik, any working USBTinyISP will program 841 without issue. There was a bug in some recent versions of avrdude that broke USBTinyISP in general (updating ATTinyCore to 1.3.2 via board manager will pull in the fixed version of avrdude)

My advice is "if it ain't broke, don't fix it". Give it a try with the current firmware and if it works then don't waste time on a firmware update.

I've never heard anything about firmware updates being available for the USBtinyISP, though I'll admit it's my least favorite of all my programmers so I may not be so tuned in to the pulse of the USBtinyISP user community.
