Noticed after I made the mistake of upgrading to Lion my Parallels became stupid with loading the Tactrix USB cable even with latest drivers and latest Evoscan/Ecuflash.

For those running into this issue which results in an error looking like this:
"Unable to connect the USB device to your virtual machine"

Open Terminal (on the Mac side),
Input the following:
sudo kextutil -t /Library/Parallels/Parallels\ Service.app/Contents/Kexts/10.6/prl_usb_connect.kext/
Input your password

Voila! Parallels' USB amnesia is fixed and now you can go back to logging via Evoscan.
