I've tried using regedit to delete the device's registry keys under HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_xxxx&PID_yyyy, but the problem persists. functioning on a file at the office and then go to the consumer and I forgot to by hand back up MyDocs and the file was not in the offline back-up. If I proceed to the equipment manger it states that it sees thé USB HASP and thát it is definitely working OK. I think this is because my (Windows 10) development PC previously had seen this VID/PID combo as having different descriptors, so it's getting confused by some bad cached stuff. Aladdin Virtual Usb Bus Enumerator Mastercam X. But when I change the firmware back to using the VID/PID that I started with, and then connect the device to my development PC, it shows up in Device Manager under "Other devices" with an error icon. Now I've gotten the device to enumerate successfully on Windows 7, 8, and 10 PCs as a WinUSB device, and I've established communication.

What are best practices on the (Windows) PC-side for testing/development of USB device firmware, during the stage when device descriptors and metadata are in flux? Is it possible to avoid chewing up PIDs just to avoid the Windows caching?īecause of the way Windows caches USB descriptors and the like from previous enumerations, during firmware development, I was incrementing the device Product ID (PID) in the firmware after each time I made other changes, to ensure that Windows wasn't caching things from previous iterations of the descriptors, and messing up stuff that would otherwise work.

Is Windows caching USB metadata the cause of the failed enumeration on this one PC?.

How can I get this to work with my desired VID/PID combo on my development PC?.

If I change the PID to some other number (new to my development PC), it does enumerate correctly. My development PC had previously tried to enumerate the device when it had the same VID/PID combo, but with different descriptors/metadata.

The device is enumerated correctly on other Windows 10 hosts, but not on my Windows 10 development PC.

The device includes Microsoft Windows Compatible IDs (WCIDs) to enable automatic installation of the WinUSB driver on the PC. The file usbd.sys doesn't get installed during the OS setup because Windows won't find any virtual USB controller hardware on an ESX server.I'm developing firmware and a PC test application for a custom USB device, using the STM32F072 Discovery board. You'll have to copy the usbd.sys from your Windows OS CD (Server 2003 or XP) \i386 to the virtual machine folder c:\windows\system32\drivers. "Windows cannot load the device driver for this hardware. I pulled a small peice of a vmware forums post about it below.

Beware of the issue with vm OS installs as they do not load the basic usb drivers into windows because they do not detect any USB devices during OS install. Connect the machine to the device via the client and voila it shows up in device manager.

Install a client on whichever machine needs the usb device. I have been running a Keyspan USB server for over a year serving USB security keys for Solidworks and a VOIP App.
