I had a 2800. Had printer and 3g modem hooked up via unpowered (powered worked as well) USB hub. Both worked great.

Moved to a 2820 - Printer does not work. 3G modem does, so does a memory stick alongside 3G modem. The only way I can get a printer to work on 2820 is to plug it in directly.

Have tried all sorts of combos with Powered/Unpowered hubs, cable lengths etc. Basically a setup that works fine with 2800 does not work with 2820.

Draytek UK said that USB function should be the same between the 2 routers and cannot explain it.

Anybody got a printer working via a USB Hub on a 2820? In which case what printer and router firmware?

Many thanks!

went and started 2 threads. got a bit more info, but gonna keep it here:
