...I didn't have the time to implement removable drive or PSP detection for this version so you have to type the drive letter, and I recommend using a capital letter.

Available functions include: Standard SCSI Query, Format Memory Stick (Device Level), Retrieve Unknown Data, Retrieve USB String, Retrieve Firmware Version, Retrieve Nickname.

NOTE: Submitting a Query for Format Memory Stick will format your memory stick. NOTE: Firmware Version and Nickname can only be pulled on Firmwares 2.00 and newer.

If bytes to pull is less than whats put out the command fails, the app is currently only setup to handle 128 bytes as none more is needed but I will allow more in the future. The app will select the known length when you change queries.
