jameszero,
Вот нашел запись в setuplog по модему.
Setup Commit File Queue() failed.
Error = 1223, Device = ZyXEL OMNI 56K PCI Plus
Installing the null driver for this device
GUID = {4D36E96D-E325-11CE-BFC1-08002BE10318}
SetupDiCallClassInstaller(DIF_INSTALLDEVICE) failed on first attempt.
Error = e0000219
SETUP: Device not successfully installed.
А с чем это жевать пока не понял.
