_UID is no matter, whatever numbers you like. The _HID, _UID pair should
make your device unique if you have to assign same _HID for several of them.
You may omit _UID at all if there is only one _HID of it's kind in the DSDT.
Cheers

Ahh, of course, _HID = EISAID("PNP0A03") = a0341d0. That helps.
Now for the _UID...
