Looking for a way to detect a connected HiMD walkman automatically and connect it in qhimdtransfer. This splits into two different questions, presented with their possible solutions:

1. Detecting Hi-MD walkmen that are already connected to the computer on start of QHiMDTransfer
   • libusb can be used to iterate over all connected devices. This is mostly platform independent, but it seems difficult to get to a path (i.e. mountpoint) from an USB device ID (bus/address or something like that)
   • libusal (or libscg) to scan for the SCSI device that the Hi-MD walkman makes available via the USB mass storage transport. No idea how easy it is to get a mountpoint from libusal bus scans. Did not look at it yet
2. Detecting when a new HiMD walkmen gets connected
   • On Linux: Listen on system DBus for DeviceAdded/DeviceRemoved events
   • On Windows: Listen for "WM_DEVICECHANGE"-Message with subcodes "DBT_DEVICEARRIVAL"/"DBT_DEVICEREMOVECOMPLETE"
   • Sample code for Windows: http://www.codeproject.com/KB/winsdk/usbdisks.aspx
   • On Mac: Listen for "NSWorkspaceDidMountNotification" / "NSWorkspaceDidUnmountNotification"-Notifications
   • On Linux/Windows: Use autorun/autoplay-like mechanism. The program called by autorun need not to present the full GUI, it might be enough to just tell an already running QHiMDTransfer the addition of a new device.

Screenshots on how the autorun-like entry works in the gnome file manager (the first image shows the file browser in the root directory of a Hi-MD medium, the second the file manager autorun properties):

While QHiMDTransfer and libhimd have become more and more powerful over the last months and we have gained knowledge about what is possible with the hardware and what not, it's time to make some plans for the first release versions of the software. He is what came to my mind:

• versioning support

• initial built-in online help

• automatic updates for Windows and MacOS X

• support for uploads on all HiMD Walkman

• support for formatting HiMDs (1GB and 60/74/80 min.)
• auto detection of connected HiMD Walkman on Linux and MacOS X

• support for AT3/3+/PCM downloads on MZ-RH1 and MP3 downloads on all models
• support for deleting and renaming tracks

• support for grouping tracks
• support for drag-and-drop uploads and downloads
• add preferences dialog (display language; setting filename pattern)
• export tracklist to text-files (HTML or XML for example, Qt has XML-Support)
• make use of statusbar to display mountpoint and space-left/overall space of HiMD

• support for NetMD downloads (all models) and uploads (MZ-RH1 only) with a new libnetmd
• new name (rebranding) for QHiMDTransfer to reflect the fact that not only NetMD is supported
• overhaul of graphical user interface
• support to open backup images of HiMDs
• support to backup HiMDs to an image
• support to convert uploaded tracks from AT3/AT3+/SP to OGG Vorbis, AAC and MP3 and save them to disk (ffmpeg)
• get the software ready for Mac App Store: http://www.apple.com/mac/app-store/
