Linux Kernel 2.4.x Driver for

CARRY USB Card Readers

Be warned: use this at your own risk !

[ last update: 2002-03-15 ]

Supported drives:

• UISA2 / UISA6 / UISC3
• UISDA / UISDC
• UISMA / UISMC

Supported slots:

• CF (Read / Write)
• SM (Read only)
• SD/MMC (Read / Write)
• MS (Read / Write) - slow: 300-340K 

Currently missing / todo's:

• SSFDC (SM) Write 
• Speedup SSFDC Mapping table build on mount / media change
• MS WP Check
• SD/MMC WP Check
  
• Test with OHCI / EHCI Controllers
  
• Make this work with uhci (currently only well tested with usb-uhci)
  Especially some descent way of BULK URB queueing to the different endpoints...
  
• More intelligent way to handle SSFDC Cards with bad sector mappings ?
  
• Make the /proc/carry interface multiple-device capable.

HOWTO

1. First make sure you have the original carry drivers running under some Win32 plattform first: www.carry.com.tw.
   This driver will NOT work with OEM Firmwares (e.g. PQI Drivers) - they may be totally different.
2. Copy the installed Win32 drivers from %SystemRoot%\System32\Driver or wherever to your Linux box (eg. to /usr/src/linux-2.4.XX/drivers/usr/storage).
   The drivers are normally named  "uiXXX.sys" / "XXXusb.sys" or similar (XXX = your device model).
   NEW: as carry has changed their drivers, see the download section for "older versions".
3. Grab the patch and apply it to some recent kernel.
   cd /usr/src/linux-2.4.xx
   wget http://www.dauskardt.de/carry_2001-11-27_fwfree.diff.gz
   gunzip carry_2001-11-27.fwfree.diff.gz (or maybe don't incase apache's already done this)
   [Maybe try patch --dry-run -p1 <carry_2001-11-27.fwfree.diff first]
   patch -p1 <carry_2001-11-27.fwfree.diff
4. Run paul's carry_make_firmware.pl script over these .dll's (.sys's). You should now have carry_firmwares.h file.
   cd drivers/usr/storage first.
5. Check the resulting file "carry_firmware.h". It must contain at least one 'loader' and one firmware for your device.
6. make menuconfig.
   Make sure you have: 
       SCSI (and "probe multiple luns"), SCSI-DISK, 
       all the USB stuff, USB-STORAGE, CARRY, Generic SSFDC, and the appropriate firmwares,
7. unplug, rmmod usb-storage, make bzImage / modules / whatever.
8. make modules_install
9. insmod your new usb-storage or configure your hotplug / usbmgr
10. plug in your reader
11. enjoy your new /edv/sdX1 nodes.

Notes:

• Watch out for odd device numbers (i.e. 0x07cc / 0x0005) - you've probably got the wrong firmware !

Downloads

• www.carry.com.tw  
  Goto the Download section and get the Win32 for firmware extraction.
  Or: [scusb.sys], or [smausb.sys]
• v0.61 - 2001-11-27 [carry_2001-11-27_fwfree.diff.gz]
  The 'latest'
• v0.4 - 2001-05-04 [carry_fw_free-2.4.4.diff.gz]
  First release.
• Possibly carry_fex.patch
  A patch by Remco Treffkorn to make carry_fex.c endian-safe (i.e.PPC)
  

 Thanks to

• Carry for the good support
• Paul Wagland for great firmware work
• Daniel Ceregatti for getting us to make this driver 'useable' ;-)
• Remco Treffkorn for the endian-patch
