Re: [linux-usb-devel] Problem with 2GB card using USB SD card reader
Hi Matthew et al., I've gotten around to creating a log of the verbose debug output when I attach the card reader with an SD card inserted. This is a multi card reader with 4 slots for different media type, the other three of which are empty. I've placed the log here: http://www.opensourcejason.info/files/usb-storage-attach-debug Cheers, Jason On 8/4/07, Matthew Dharm [EMAIL PROTECTED] wrote: Can you do the following: 1) Dump the partition table with fdisk, and send it to us 2) Turn on USB_STORAGE_VERBOSE_DEBUG, capture the log from inserting the card and capacity scan, and send it to us Matt On Sat, Aug 04, 2007 at 12:10:07PM -0700, Jason LeBrun wrote: Hi there, I'm using a Kingston 2.0GB SD card with a unbranded card reader (model number UCR-61).

Sorry for top-posting (darn pocket outlook). Perhaps widnows does some test-reads to check the size?

When I insert the card, it's detected as device using 512-byte sector sizes This is correct. All SD and SDHC cards are using 512 Byte sector size. , and therefore it only shows up with about 1GB. The card reader fails to compute the right sector count. The only thing you can do about it: buy a new card reader. (You should buy a reader which is also capable of using SDHC cards IMHO). I've poked around the mailing list, and I've found that a few other people have mentioned this problem, and the responses to date seems to imply that it's a hardware combination problem rather than a driver problem. It's a card reader problem. It's the same with ALL 2GByte SD cards. I understand that one of the issues is that certain readers can not properly handle 1024-byte block sizes 2 GByte cards report a sector size of 1024 bytes. The host (==the card reader) is assumed to calculate the SD card size with these 1024 bytes. For all I/O operations, the host is assumed to use 512 bytes. Your card reader fails to implement this hack - invented for 2GB SD cards - correctly. , but I don't think this is the case here. If I use the same reader-card combination on a Windows machine, the card is recognized as a 2GB device. H...

If the poster uses d and /dev/null to Ero the start of the card, and then checks how windows deals with it, we will soon know. I think it is worth having a blacklist or module options to indicate that the USB host needs to implement the 2GB hack. Generally - as there seem to be many hack and quirk lists building up - I'm tending towards preferring a text database of such quirks that can be updated seperately from kernel releases. This would make it simpler for many techie-but-not-kernel-hacker users to provide such information. As an example it took me half an hour to test the quirks for a quad usb hid device using khexedit to patch in a usb-I'd to an existing driver. It took 8 hours to get a kernel compiled and patch. I still don't have time to verify if both quirks for another dual usb are actually required and so that patch isn't adopted yet. Anyway... Sam - This SF.net email is sponsored by: Splunk Inc.
