its your hub.. at 200M you are right at the .9A most hubs can put out..
try going down to 196.88
Sorry, I should have mentioned. Now that I am troubleshooting, I'm running at 125mhz, just to se if it'll perk up. Doesn't matter, on the hub or direct connected to A PC, it just want start hashing.
The other unit runs fine, at 200 MHz still. Both were running for weeks with no issues until the reboot.
Try plugging the one in after cgminer is running (hot plugging it).
Tried that just now. Tried starting with nothing plugged in, and then plugging in the stick, but got the same error (No valid hashes for over 10 secs, attempting to reset). Tried starting with the stick in, and after it failed, tried unplugging and replugging. No luck.
I'm going to try compiling VH's versions of cgminer, and see if that shows anything different.
Is there anyway to check/debug whats going on?
