Toth, the flash versions also had several different internal CPU/DSP speeds
(issue ATI7 command to the modem), and USR was very plain that while the
slower models with flash were upgradeable, they would not achieve the
connection speeds of their faster siblings. Mine happens to be an older
flashable model, and my experience was exactly as USR advertised: the
upgraded modem never connected at the same rate as a newer model of the same
modem with X2/V90 out-of-the-box. I have a (server) folder of USR stuff, I
tend to be a packrat about software, and I've got this goodie called the
"3Com Internet Update Wizard" dated 10/4/1999, which seems to be the flash
updater (it downloads a flash file from USR to apply). I also found some
downloadables for updating at http://www.usr.com/infinity/.
