There's a prospect of it supporting just about anything that plugs into a USB port. Converting a prospect to a working driver is another matter entirely.
The main problem is going to be that you only have one serial channel to the USBWiz. So, if you're doing I/O with a USB flash drive, or the internal SD card slot, the keyboard would be blocked until at least the completion of the current Read Sector or Write Sector command. This would feel especially painful because the Ser-USB driver does fully asynchronous writes, returning the cursor almost instantly, even though the data might take many seconds longer to write. In this time you would try pressing a key and nothing would happen :( That said, I could probably enhance the driver to support multiple USBWiz's on different serial channels, but it would be a tad expensive as a hardware proposition. I have built hooks into the driver to support piggy-back processes, allowing other transactions to happen when the serial channel is free; but that facility would be woefully inadequate for any real-time transactions such as key presses or mouse movements. btw I am aiming for a test release of the driver to anyone who is interested around mid March. I have been concentrating on improved memory management, performance, compatibility and extensibility. The driver now contains no QUBIDE-era hardware interface code! Current build is 0.03.019 with support for the superHermes SER3 fast serial port. It runs happily on Aurora/SGC, but an unexpanded QL is problematic (slow ports, insufficient memory for adequate buffers).

Any prospect, USBWiz thread, that the USB driver could support a USB class keyboard? _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
