Hi,
Someone helped me to find out the problem.
Your USB device is reporting an invalid USB version (USB version 10.01, rather than 1.0, 2.0,2.1 or 3.0 which are the current existing USB versions):
High USB versions are required to supply a BOS descriptor. Starting windows 8, MS enforces this and fails enumeration for devices that do not supply a BOS descriptor:
For Windows 8 MS supplied a workaround, I assume this will work also for windows 10, but I don't have the actual device in order to test:
Workaround
To apply the workaround for a specific device, add a REG_DWORD value named SkipBOSDescriptorQuery that has a value of 1 to the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\usbflags\vvvvpppprrrr
(where vvvv is the device's Vendor ID, pppp is the device's Product ID, and rrrr is the device's Revision number. You can get the VID/PID/REV numbers from the device manager's details tab. This number is encoded in the HardwareIDs of the device)
1. Click Start, click Run, type regedit in the Open box, and then click OK .
2. Locate and then click the following subkey in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags
3. On the Edit menu, point to New, and then click Key.
4.Type the name of the new key in the following form:
vvvvpppprrrr
where
vvvv is a 4-digit hexadecimal number that identifies the vendor (idDevice from the USB Deviceescriptor),
pppp is a 4-digit hexadecimal number that identifies the product (idVendor from the USB Device Descriptor)
rrrr is a 4-digit binary-coded decimal number that contains the revision number of the device
(bcdDevice from the USB Device Descriptor).
5. On the Edit menu, point to New, and then click DWORD (32-bit) Value.
6. Type SkipBOSDescriptorQuery for the name of the DWORD Value, and then press ENTER.
7. Right-click SkipBOSDescriptorQuery, and then click Modify.
8. In the Value data box, type 1 , and then click OK.
9. Exit Registry Editor.
10. Unplug and re-plug the device for the workaround to take effect.
Creating the registry key bypasses the problem.
Thanks to all for the efforts !!
