Windows driver INF file change

Technical Support & Q&A
1

A small problem I have with Orbbec cameras is that on Windows the driver does not successfully install if its behind a usb hub. This creates a lot of inconvenience directing users to manually install the appropriate driver by going through the device manager.

I think this is because its a composite device issue, and to fix it,
obdrv4.inf needs to be modified,
%USB\VID_2BC5&PID_0400.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0400&MI_00
%USB\VID_2BC5&PID_0401.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0401&MI_00
%USB\VID_2BC5&PID_0402.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0402&MI_00
%USB\VID_2BC5&PID_0403.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0403&MI_00
%USB\VID_2BC5&PID_0404.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0404&MI_00
%USB\VID_2BC5&PID_0405.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0405&MI_00

changed to
%USB\VID_2BC5&PID_0400.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0400
%USB\VID_2BC5&PID_0401.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0401
%USB\VID_2BC5&PID_0402.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0402
%USB\VID_2BC5&PID_0403.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0403
%USB\VID_2BC5&PID_0404.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0404
%USB\VID_2BC5&PID_0405.DeviceDesc%=obdrv4.Dev, USB\VID_2BC5&PID_0405

for both [Orbbec.NTx86] and [Orbbec.NTamd64]

I am wondering if this is something you guys want to do as it would save me a lot of trouble resigning the drivers with my own certificates.

What sensor type do you have. When did you receive the sensor. What are the numbers on the back. This will help Orbbec fix the problem.

Hi IronPlanet!

I have the Astra S, I got the one with new PCB version.

Out of curiosity, do you not have this problem? If you uninstall the current driver and reinstall it, attach any Astra device to a USB hub and then attach it to the computer, would the drivers install automatically under Windows or do you have to manually specify the driver to use?

I think the problem is not specific to a particular camera model, it is simply the hardware ID matching rule in obdrv4.inf that came with SensorDriver-4.4 is too stringent.

Hi,

I have the same issue as you had but seems that updating the INF doesn’t solve the problem.

Do you have suggestion how should I proceed?

Thanks
