USB sleep fix

Device (HPET)
Name (_HID, EisaId ("PNP0103"))
Name (_CID, EisaId ("PNP0C01"))
Name (CRS, ResourceTemplate ()
Memory32Fixed (ReadOnly,
0xFED00000, // Address Base
0x00000400, // Address Length
OperationRegion (^LPCR, SystemMemory, 0xFED1F404, 0x04)

HPTE, 1,
Offset (0x04)

Method (_STA, 0, NotSerialized)
Return (0x0F)

Giving the HPET status a 0x0F seems to fix my USB sleep issue, loosing USB after sleep and no Hot plug on USB ports.

This is not verified, as I did not try to reproduce the problem, not on my piriority list, but my system run 10.5.6 vanilla, with Decrypter, AnV SMBIOS, PS2nub and Controller and openhalt.

No IOUSB fixes. ( it crash my system.)

Update -- this is fixed by DSDT Patcher with -newHPET option. no need Disabler after the patch.

ASUS EEEPC 1000H - Atom N270 - 2GB RAM, 500GD HD.
OSX 10.5.6 (vanilla)

Gigabyte P35-DS3L, E2180, 2 GB RAM, 2 1 TB HD, GT8800 512M.
