40	Beeps and Hangs with USBHCD188 drivers	losepete	somebody	"Having rebooted after installing the files from USBHCD188.ZIP (except the USBD.SYS files, see ticket #39) my system was giving a ""beep"" now and again - the sort of noise that indicates a possible hardware problem. 

After around 30 minutes the system hung and needed to be rebooted by pressing the Reset button on the system box as Ctrl-Alt-Del did not work.

Around 30 minutes after rebooting the system hung again.

Either the system has a developing hardware fault or there is a problem with the USBEHCD.SYS and USBOHCD.SYS files from USBHCD188.

I was previously using the USB?HCD.SYS files from USBHCD185 so have reinstalled those files and rebooted to test whether the system ""beeps"" and hangs disappear. If they do disappear I think we can conclude there is a problem with the files in USBHCD188 ...


Later: It is approximately 1 hour since I typed the above sentence and the system has not ""beeped"" once and has not suffered any hangs since rebooting with the USBHCD185 files installed. It seems the problems arise from using the files in USBHCD188.

The only USB devices currently in use and during testing of USBHCD188 files are a Microsoft USB trackball and an *internal* USB multi cardreader. The trackball is USB1.0; the cardreader is a USB2.0 device.

The mainboard chipset is nVidia NF430 with 1 OHCI and 1 EHCI controller.
