I'll try and keep this short and simple.
DESCRIPTION OF PROBLEM & WHAT I'VE TRIED
I have a no-name wireless mouse & keyboard combination (USB Composite device) which works great when I start the PC up.
However when I put my PC on standby and then waken it up again the mouse & keyboard do not respond and I have to remove and replace the USB 'transmiter/receiver' stick, to get them working again. I've tried all USB ports with & and without other devices in other ports but they still do not respond after wake up.
When I enable device under 'power management' to bring computer out of standby they work BUT I suspect it only puts my PC into S1 standby due to the fact that the fans are still running while on standby.
I have also checked under 'device manager'and noticed that the USB Composite device power capabilities only goes as far as PDCAP_WAKE_FROM_D2_SUPPORTED. I take it if it was D3 supported they would work after coming out of a D3 standby.
If D3 refers to the S3 standby level, is there anything I can configure that will make the composite device PDCAP_WAKE_FROM_D3_SUPPORTED?
Is there anything I can configure to enable device/s to put/bring PC into/out of S3 standby?
Has anyone got a wireless mouse/keyboard set that DOES work when coming out of a normal standyby?....(if so what have you got?...cos I want one too
Many thanks in advance, misterc.
