pavilion webcam linux

[Wolfmann]

Hi 🙂

I just installed Ubuntu 16 on a HP Pavilion dv1000. Everything works well, except my webcam. I have spent countless hours searching for and installing linux drivers, but no luck. Starting to think that it may be a hardware issue? Can anyone help me try to troubleshoot this?

Thanks...

Did the webcam work in Windows? 

Have you tried installing and launching Cheese in Ubuntu just to test the webcam?

I don't know if it worked in Windows. Yes, I installed Cheese and it didn't see the webcam. Tried an external USB webcam and it worked fine.

I had tried the suggestions at https://help.ubuntu.com/community/Webcam

Assuming that the hardware is okay because I can see the webcam when I run the following:

$ lsusb

Bus 001 Device 003: ID 05ca:1870 Ricoh Co., Ltd Webcam 1000
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 03f0:171d Hewlett-Packard Bluetooth 2.0 Interface [Broadcom BCM2045]

$ sudo lsusb -v produces:

Just found out that the internal card reader (SD etc) is not working either. It must be a driver issue and I'm not familiar enough with Linux yet in order to troubleshoot it. Doing lots of reading online, but still hoping that someone here can help me to get those devices working....

[Wolfmann]

I will keep updating as I make progress troubleshooting this... it may help someone in the future.

As already posted above $ lsusb shows the USB devices in the system:

Bus 001 Device 003: ID 05ca:1870 Ricoh Co., Ltd Webcam 1000
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 03f0:171d Hewlett-Packard Bluetooth 2.0 Interface [Broadcom BCM2045]
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 04f3:0232 Elan Microelectronics Corp. Mouse
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

My webcam is Device 003, which implies that the hardware is recognized by linux.Adding the -t option to the command shows the physical USB device hierarchy as a tree and it also shows the associated drivers:

$ lsusb -t

/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
    |__ Port 2: Dev 2, If 0, Class=Wireless, Driver=btusb, 12M
    |__ Port 2: Dev 2, If 1, Class=Wireless, Driver=btusb, 12M

    |__ Port 4: Dev 3, If 0, Class=Imaging, Driver=, 480M

Apparently, there is no driver attached to my webcam... this is helpful information as I narrow down the problem. Will now focus on finding a driver...

[Huffer]

Apparently this Ricoh webcam used in HP laptops is a bit of an orphan. Here is a driver site.

Thanks for the answer... Did install the r5u87x driver yesterday, but no success. That must mean that my webcam uses the WDM chipset.

I'm relatively new to linux, so compiling a driver looks painful. Will give it a try later...
