Quirks/Known Issues

• When connecting a device, have the cable connected to the device and adapter first, then connect the adapter side to the calculator. Otherwise, the usbdrvce library won't be able to reset the connection.

Successful Tests

• Putting an iPhone 3G into DFU mode from WTF mode by sending split up WTF files (split -n 2 wtf.bin and convbin...) from an iOS 4.2.1 IPSW.
• Sending an iBSS, iBEC, and Recovery Mode picture to an iPhone 4 in PWNDFU mode (pwned on a mac), then sending the setpicture 0x1 and bgcolor commands.
