Theoretically you can have 256 devices. Realistically it's tough even on a linux machine with quality drivers to go to 25+. I fear where you can get on windows without issue.
Troubleshooting you can do: Get things as close to the root hub as possible, use powered USB hubs and move around the device giving you problems to see if a different USB root hub or path works better. If needed, buy a new USB card and see if that works for it. Not many people get this many devices on a system. On Sat, Jul 12, 2014 at 8:08 PM, DSinc <[email protected]> wrote: > Joy for Grand-PA!
