Some USB devices need a power cycle after a deactivation or a loss of the USB connection, to be able enumerate themself again at the host. This is what is happening when you power off or reboot your virtual machines.
We can automate the power cycle of the USB ports on the DongleServer whenever these devices are connected. The following steps will cause the specified USB device to power cycle for 5 seconds after every interruption or deactivation of the USB connection.
1. Download the parameter file from the dongleserver (Maintenance > Backup > Export)
2. Delete every entry in the file except the “utn_poffduraX = 0” entrys, where X is for the USB port number where your Telium Dongle is plugged in.
3. Change the 0 to a 50 in the above line, and save the file.
4. Upload this file to the dongleserver
5. Verify this parameter was accepted via the “view” button on the “maintenance” -> “backup” page.
For example, on a 20 port DongleServer ProMax the new config file to upload would look like this:
utn_poffdura_1 = 50
utn_poffdura_10 = 50
utn_poffdura_11 = 50
utn_poffdura_12 = 50
utn_poffdura_13 = 50
utn_poffdura_14 = 50
utn_poffdura_15 = 50
utn_poffdura_16 = 50
utn_poffdura_17 = 50
utn_poffdura_18 = 50
utn_poffdura_19 = 50
utn_poffdura_2 = 50
utn_poffdura_20 = 50
utn_poffdura_3 = 50
utn_poffdura_4 = 50
utn_poffdura_5 = 50
utn_poffdura_6 = 50
utn_poffdura_7 = 50
utn_poffdura_8 = 50
utn_poffdura_9 = 50
