When connected to the computer audio files can be copied to the MP3 player. When the MP3 player is connected to FreeBSD it takes some seconds until the corresponding entries appear in `dmesg`. umass0: vendor 0x10d6 Generic USB Disk Device, rev 1.10/1.00, addr 2 da0 at umass-sim0 bus 0 target 0 lun 0 da0: Removable Direct Access SCSI-2 device da0: 1.000MB/s transfers da0: 249MB (510494 512 byte sectors: 64H 32S/T 249C) /dev/da0* entries are not available. When the device is detached FreeBSD usually goes into the debugger. To connect other USB memory sticks is no problem. >How-To-Repeat: Boot FreeBSD.
