I installed an ESS Modem driver which works great on Ubuntu but after updating the OS, the driver never stays installed. When I first installed Ubuntu9.04 it showed up in Hardware Drivers and kept installed even after rebooting. After updating, every time I reboot it no longer shows up in hardware drivers and I have to install the driver. It says /dev/modem not found or something. I tried setting GnomePPP to the /ttyESS or whatever it was, which is where the driver is apparently installed according to the driver's readme, (I can't remember the path but I pasted it at the time) and it didn't work. The driver works perfectly, I just wish I could keep it installed after a reboot to save the hassle of installing it each time. Updating Ubuntu must have done something.
