I have 3 UHCI and one EHCI devices (and drivers installed) on a VIA VT8237 chipset laptop with a mobile AMD Athlon 64 3200+ CPU running eCS 2.0 with UNI kernel and ACPI.PSD /Q.

With the original IBM USB drivers loaded, only the EHCI shows up in the hardware manager. USB 2 devices are recognized, USB 1.1 devices are not recognized when plugged in.

If I use the USBUHCD2.SYS drivers instead of USBUHCD.SYS for the USB 1.1 devices, then UHCI shows up in the hardware manager (along with EHCI) and all USB devices attached are recognized.

Up to version usbxhcd6 of the Netlabs drivers the behavior is exactly the same as the original IBM drivers.

Version usbxhcd7 now shows the UHCI devices in the hardware manager, but USB 1.1 devices are not recognized when plugged in (USB 2 devices are).

Hi Lars, hi Greg,

first of all many thanks for your hard work. I have used all your builds (1-8) in the past. I mainly attach sometimes a WD MyBook external hard drive and had no problems so far. The only difference is that with your driver my backup is much faster.

But yesterday i found out, that there is another problem. Starting with build 7 of the driver my camera is no longer able to connect to the pc. After some minutes, the camera thinks that the connection is established, but i can't use the drive from OS/2. Additionally the boot process has changed. The boot stops for nearly one minute during loading ndfs32.ifs (NetDrive latest available version).

Both problems are gone if switching back to build 6.

I have a dual core AMD machine here with acpi 3.18 running. If i can provide more info, please let me know.

This was originally posted in comp.os.os2.misc/Update to USB host controller drivers: usbxhcd8.zip but does not seem to have had any response to date:-

There seems to be a problem with the included usbohcd.sys driver; usbehcd.sys seems to be working fine but cannot test usbuhcd.sys.

I unzipped the usbxhcd8 package and powered off as it was (past) my bedtime.

Today I powered on the system and was surprised to see the boot process stop with this onscreen:-

USBMOUSE.SYS: USB MOUSE driver v.1.1 loaded.

I rebooted but the boot stops at the same point - I went and made a coffee and the boot process was still at the same point on my return over 5 minutes later.

I booted to a cmd line, deleted usbohcd.sys and reinstated the IBM version.

I rebooted to a working Desktop without problems.

I'm sure that the usbxhcd7 version of usbohcd.sys did not cause any boot problems previously so I unzipped that version and rebooted to check. No problem on reboot, system loaded fine - using it to post this report.
