Following up on previous correspondance, I can confirm that both models of the FujiFilm USB SmartMedia readers (the obsolete SM-R1 and the current SM-R2) work OK with FreeBSD 4.3. In fact, they seem almost identical, apart from the fact that the case is now painted gloss purple rather than matt grey. On the inside, the PCB has had a re-layout but appears to have much the same chipset. They've forgotten to private-label the firmware in the new version: SM-R1 (empty): umass0: Fuji Photo Film SmartMedia R/W, rev 1.00/1.00, addr 4 umass0: Get Max Lun not supported (STALLED) da1 at umass-sim0 bus 0 target 0 lun 0 da1: <GENERIC SmartMedia R/W 1.00> Removable Direct Access SCSI-2 device da1: 650KB/s transfers da1: Attempt to query device size failed: NOT READY, Medium not present SM-R2 (with card loaded): umass0: Hagiwara Sys-Com SmartMedia R/W, rev 1.10/2.00, addr 5 umass0: Get Max Lun not supported (STALLED) da1 at umass-sim0 bus 0 target 0 lun 0 da1: <HAGIWARA SmartMedia R/W 2.00> Removable Direct Access SCSI-2 device da1: 650KB/s transfers da1: 62MB (128000 512 byte sectors: 64H 32S/T 62C) Performance is good: reading through the filesystem gives a shade over 700Kbyte/sec; reading the raw device depends on the block size - with a 32K block size you get the same 700Kbyte/sec, down to about 80Kbyte/sec with 512byte block. Writing is slower - about 150 to 200Kbyte/sec. Software notes: 1) Hot-plugging the USB doesn't work: the device has to be connected at boot time for it to get properly associated with the CAM subsystem (doesn't matter if there is a card in the drive or not). After attempts to hot-plug, "camcontrol devlist" reports that the USB device is associated with pass1 but not da1, and "camcontrol rescan 1" hangs forever, sometimes leading to a panic if you then unplug. 2) The USB controller gets scanned before the SCSI controllers (at least in my system), so you need a kernel with the SCSI devices wired down if your root is on a SCSI drive (to avoid trying to mount root from the smartmedia). 3) The standard SmartMedia formatting has a full FDISK table and a DOS filesystem on it, so "mount -t msdos /dev/da1s1 /mnt" is required to mount a card written from a camera. 4) "camcontrol eject da1" turns off the drive active LED allowing the card to be removed (Fuji seem to be paranoid about this: there is a sticker on the top warning you not to try removing the card while the LED is on; there's a sensor attached to the eject lever that (presumably) allows the firmware to power down the card if you press the lever intemperately, and in any case the contacts on the card are designed so that GND disconnects last and so you'd be unlucky to blow it up anyhow). 5) "camcontrol format da1" will re-write the low-level format. This is useful if you have cards that have been used in a Rio MP3 player: the Rio uses a proprietary low-level format, and my (olympus) camera refuses to touch cards that have been used in the Rio, even with the menu option to format the card. After a low-level format in the reader, the camera is then happy to high-level format the card and you are back in business. As an aside, I also tried a very cheap smartmedia reader: ugen0: SCM Microsystems Inc. SCM eUSB SmartMedia , rev 1.00/1.00, addr 5 This is sold here as the "Cardport Swift" and claims to be made in the UK, (though I have my doubts, given the above ident string and I am fairly sure I've seen this OR-gate shaped housing elsewhere - see http://www.premierelect.co.uk/CARDportSwift.html for a picture). This unit does NOT work with FreeBSD. Compared to Fuji's concern over ejecting, this unit has no LEDs or eject levers at all - you just yank the card out when you feel like it. Surprisingly, their supplied Windows drivers don't crash when you do this. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
