Hi, is it possible to transmit a very long string descriptor?
For example more than 100 bytes? More than 1000 bytes? Is there a theoretical limit in USB?
I do V-USB on a very limited ATTiny2313, so it is not possible to store the whole string in memory. I need to truly generate it dynamicly (during transmitting). Can you please give me a hint how to do this with this stack?
Kind regards,
Frank

Re: very long string descriptor
Well v-usb originally had a bug that I fixed. See details here

Assuming that is now a permanent fix ( and I believe it is ) then your limit is quit large. For example I use the FFB descriptor. See here post #36
