I've been lucky untill now regarding this computer being very stable and not being required to fiddle with stuff like, UGH, drivers.
I am doing some work toward some automatic APRS messaging and need at least three serial (232) ports on this Vista 32 Toshiba Satellite laptop.
The latest FTDI CDM Driver (vers 2.08.30.0) instaled "successfully", but won't work for a new Sabent USB<>serial converter - Device Manager reports it is functioning correctly, yea, right! HyperTerm can't open that assigned COM port and in my Visual Basic application, the Kernel32 call to CreateFile Fails.
In addition, a previously working driver for another FTDI device now has the same identical 'can't open symotpms after the install whether the new Sabrent is plugged-in or not. Uninstalling the new driver, fortunately restores the older driver for the wireless link to proper operation...
I already have a wireless (X-Bee) USB<>serial link that works just fine and has an FTDI chip. Vista, some time ago, automatically installed the FTDI driver (1.0.2134.0) for this.
Now, I got two Sabrent CB-FT1K USB<>Serial, FTDI, converter 1ft cables. (I was gonna' get the ones Stephen Smith recently posted about from NewEgg, but I missed the deal deadline and got two $10 one foot versions instead). The Sabent units also use FTDI (I'm avoiding Prolific due to the China syndrome. (;-).
Vista automatically went on-line and looked and installed that FTDI CDM driver 2.08.30.0 when I plugged in the Sabent unit.
