I have this usb device but running OpenBSD did not recognize it.
Trying to troubleshoot I saw that the device has a device descriptor of 0x00
instead of the expected 0x01 as the following debug message shows:
usbd_new_device: adding unit addr=5, rev=110, class=0, subclass=0, protocol=0,
maxpacket=8, len=34, speed=1 bDescriptorType=0 UDESC_DEVICE=1,
USB_DEVICE_DESCRIPTOR_SIZE=18

GlidePoint" rev 1.10/1.30 addr 5
uhidev2: iclass 3/1
ums0 at uhidev2: 3 buttons, Z dir

This patch allowed the device to be recognized and started working.

Does the patch look correct or the problem is not on the usb device itself?
Here is the dmesg with the patch applied, without it device is not seen
