I was using DVI2USB 3.0 on a Ubuntu host for a while and I had been able to capture images using the device.
About 2 months ago, I found that the capturing software was not working anymore. I examined the software today to trying to get it working again, but I failed.
The ubuntu host is a dell alienware notebook.
The release ID of the ubuntu os is “16.06.6 LTS”.
“uname -a” returns
" Linux myhostname 4.15.0-101-generic #102~16.04.1-Ubuntu SMP Mon May 11 11:38:16 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux"
As I suggested, I had been able to run v2u on this host. Now, I cannot run it.
On the Ubuntu host,
“lsusb” command returns “Ephiphan Systems Inc.” string.
I can see the device file “/dev/vga2usb0” when the device is connected to the USB port.
The LED indicator of the device is blue and blinking when the device is connected to the USB port.
In the SDK sample software like v2u, call to “FrmGrabLocal_Open()” fails. Thus, it seems that the software cannot find the device.
I tested the software with and without sudo.
I re-installed Ubuntu drivers from
but no changes found.
I tested the device on other Windows 10 host. Then, the device is working correctly.
What should I do next?
