apple wireless keyboard and mouse re-pair

I have a custon ASUS m48A89GTD MOBO runnin windows 7, and a apple wireless keyboard and magic mouse with a cheap generic USB bluetooth dongle, which runs on a "broadcom 2.0 + USB dongle driver"

The keyboard and mouse pair with no problem, i can restart the pc and re-pair the devices perfectly.

However, if i manually remove the dongle and reconnect it, all pairing info is lost and have to re-pair,

While the pc is shut down, the dongle remains lit with a "standby" power supply, If i remove the dongle and reconnect it, even if the pc is off, the problem repeats itself.
same goes if i disconnect the pc from the wall outlet

Apparently the dongle has to remain "powered" for it to remember all the pairing and devices info.

this is quite annoying, because i have to whip out my wired keyboard to re-pair every time this happens

has anyone had this problem before?
any suggestions or help? please?

Thanks

clarification

I should clarify, that if remove the dongle i have to re-pair manually, input the device code and all that,

if i dont remove the dongle the re-pairing is done automatically.

which means that if i remove the dongle while he pc is shut off, when i power on, i have to use the wired keyboard to log in, and pair the devices again
