Hi,
As part of an OS update project there are approx 100 devices with DisplayLink screens being upgraded from Ubuntu 18.04 to Ubuntu 22.04.
There are 2 models of DisplayLink screen involved, the first model has upgraded correctly and works without any problem. This one shows up in `lsusb` as below
Code:
idVendor 0x17e9 DisplayLink
idProduct 0xff00
bcdDevice 47.60
iProduct 2 OLC-TOUCH10.1
iSerial 3 1179322TWJANL461743
The second model of screen has stopped working after the update and refuses to work even when the OS is rolled back to Ubuntu 18.04.
This is the screen before the update:
Code:
idVendor 0x17e9 DisplayLink
idProduct 0xff00
bcdDevice 74.37
iProduct 2 OLC-TOUCH10.1
iSerial 3 DSIP293TWJANM200232
After the update the screen stays blank, the serial number has changed and it is showing up as being in a manufacturing test mode:
Code:
idVendor 0x17e9 DisplayLink
idProduct 0xff00
bcdDevice 74.37
iProduct 2 Manufacturing Test Mode (Basic)
iSerial 3 DSIP293DL4121-02.A5D.934
All this type of screen we have tried so far (5) have failed in the same way.
Please can you advise how we can recover these broken screens and how we can upgrade without having this issue?
