I use Motorola Mobile Phone Tools with my cell phone to work with the phone book, calendar, graphics, ringers, and videos. To copy/synchronize between the phone and the PC. It seems that using a USBSER.SYS file newer than the 8/8/2000 version causes problems for MPT communicating with the phone. I am using WinXP Pro w/SP2 and all of the latest windows updates applied. When I replace the file with the old version, it will be ok for a while, but then the new one comes back without warning. I am assuming due to SFC? I have replaced the file in C:\WINDOWS\system32\drivers and C:\WINDOWS\system32\dllcache in normal and "safe" mode. How can I keep this ONE file from being "updated" back to the version dated 2004? Can I modify the INF file that is used to install my phone via usb cable as a "Motorola USB Modem" so that it copies this older USBSER.SYS onto the system when installing the device? or is there some other way?
