Hi everyone!
I have 3 usb hubs with 10 ports each. 28 USB tokens plugged there. They are used by accountants to sign up documents. My problem is - after few minutes USB tokens switch to suspend mode and random of them will not wake again, so I forced to re-plug them.
I have tried:
1) To turn off «USB suspend» in Power management and in hub settings (Device Management) – no result. All power-safe features turned off in BIOS (Supermicro X9SRI-3F REV: 1.20).
2) To Turn On or Off USB Selective Suspend Setting in Command Prompt

3) Disable Selective Suspend feature

I dont have "pure" USB registry subkey - so I created DWORD "DisableSelectiveSuspend" in every usb* registry subkey.
My workaround is reset main hub in computer management if token don't answer.
