    Having a USB-connected device using a FTDI usb-serial driver on the Mac OS X side of things, is there a way to map a VM XP-guest serial port to the Mac OS X driven usb-serial bridge?

    ( Using Parallels Desktop for Mac RC1 and a XP-SP2 guest. )

    In the beta versions of Parallels, there seemed to be an unimplemented option to map a client serial port to a host serial port (the option "map to a real serial port") as it was a checkbox among the other 2 options (map to a file or a pipe) but the checkbox was disabled. It has since been removed in the RC, which was disapointing. Had they implemented it, it would have been one less USB device to worry about. So currently, there is no way as I can tell to map a COM port to a Mac serial port as the USB support is still broken.

    I tried (the author was kind enough to make it available) it and unfortunately it did not work for me. Since I need to be able to change the port speed on the fly (the device starts at 9600 baud, then the software ramps the speed up, I did not spend a lot of time on it, so I assume I would have gotten it to work with a little fiddling.

    Cheers,

    SmartCard reader using XP FTDI drivers fixed by RC2

    Okay, I was looking after the above because since introduction of USB and until RC1, writing a smartcard from my XP guest was failing. It was kind of working, but always failing during transfer for kind of "synchronization errors" at some point (sometimes 10%, sometimes close to 99%, but it was always failing).

    I am writing to confirm that using RC2, it seems fixed. I could read and write multiple times two different smartcards minutes ago from within my XP guest, so using the FTDI XP drivers.

    This is a really good news !!
