--17pEHd4RhPHOinZp Content-Type: text/plain; charset=iso-8859-15 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello all, I got this lousy MP3 Player/USB Stick, and ever since I tried to upload/download some stuff from within FreeBSD it's horribly slow. I tried it with 4.something back then and even 5.4 with the updates to the USB stack didn't improve the situation. Here's the device port 3 addr 5: full speed, power 100 mA, config 1, MP3 Flash Stick(0x1004), Co Ltd(0x11e9), rev 1.00 Using cp to/from the FAT16 partition or using dd(1) on the partition results in 4kB/transfer and it even manages to bogs down the I/O throughput of the whole system (even though PREEMPTION is on). tty ad0 da0 cd0 cpu tin tout KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us ni sy in id 0 229 16.00 1 0.02 4.00 14 0.05 0.00 0 0.00 46 0 3 2 49 0 383 2.00 9 0.02 4.00 14 0.05 0.00 0 0.00 37 0 5 0 59 0 478 0.00 0 0.00 4.00 14 0.05 0.00 0 0.00 27 0 7 0 66 0 387 2.00 2 0.00 4.00 13 0.05 0.00 0 0.00 26 0 5 1 68 1 229 0.00 0 0.00 4.00 14 0.05 0.00 0 0.00 2 0 7 0 91 0 488 0.00 0 0.00 4.00 14 0.05 0.00 0 0.00 5 0 6 2 87 usb_quirks.c has nothing to offer, that springs to mind (except perhaps a typo in line 89, "farmware" ?) ISTR that there were some USB and/or SCSI (CAM?) quirks one could tweak. Could someone point me into the right direction please? Ulrich Sp=F6rlein --=20 PGP Key ID: F0DB9F44 Encrypted mail welcome!
