Have run into a number of problems with one USB flash card reader and two types of flash memory cards (SD and CF).

The flash card reader is a recently bought high speed hama 35 in 1. This device simply isn't recognized by Puppy. The power light goes on, but pmount shows not USB devices on the system. Three older card readers show up and work every time.

The same hama reader works fine under Win2K.

The to other problem occurs with 2GB SD and CF cards. The SDs are Kingston brand. The CF is a SanDisk Ultra II.

Under Puppy, they show corrupted files, and can't be written (they're designated write protected). The files that aren't "corrupted" can be copied, but not deleted.

Under Win2K, there's no problem. There are no corrupted files, and no problem deleting or writing to the cards.

A 1GB Kingston card of the same model causes no problems. An older 2GB Fujifilm "M" type XD card also reads and writes fine under Puppy.


Very frustrating.

Anyone know of a solution or even an explanation?

I'm wondering whether it's worth burning a Knoppix DVD to see if these problems are generic to Linux or just more Puppy doodoo.

As a Puppy user for over two years my advice to you is to go to Puppylinux.com and log in or Register first and then proceed to the place where you can likely get your answer. It is called the "Puppy Discussion Forum ::Index. Here you will find over 24,000 topics for Beginners and Users; 150,000+ posts and 343087 articles.....More importantly, when there if you cannot find what your looking for in already started threads you can post your own inquiry to the whole of the Puppy world. Puppy has been around since May of 2005 and is extremely small, useful, powerful, adaptable, and mostly backwards compatible with many very old computers that would parted out but seem to work fine with a particular Puppy derivative. That said: there are many derivatives based on older versions of the Linux Kernal(s) and some of those work better with certain computer configurations. The Administrators and those who use Puppy daily will find a solution for you I am sure. This has to be diagnosed by someone who has the same equipment as you describe or of similar in nature to yours. And I do not have such devices. The other solution would be to trade off the cards or flash drives that don't work with your system for ones that do. Cheers Mate. BigBearJoni.

I participated in those forums for almost a year myself, posting about 600 messages, until I was summarily banned from it about a year ago. Although I agree that it's the ONLY place to find solutions for Puppy problems, a look at the vast number of unsolved problems that linger there shows your response to be wildly optimistic.


Ah yes! The classic Linux solution - dump your hardware that works perfectly in even the most ancient Windows OS and keep buying replacements until you find something that also works under Linux.

thanks so much!

If you enter lsmod in rxvt, do you get hci_usb, ohci_hcd, usbhid, usb_storage, and ehci_hcd?
I am wondering if ehci_hcd is missing, which tends to be needed for newer devices.
If so, enter modprobe ehci_hcd and see if it works.

ehci_hcd is there. I did a bunch of other testing, and wasted a good half hour typing a very detailed account of all the errors that resulted and when I hit preview, it was all gone. The forum software had logged me out.

Total waste of time. I should have known better anyway than to post Puppy problems, especially here.

The distro is barely adequate for casual unprotected web browsing, and maybe some graphics editing, but not much more. It will never be a Windows replacement, or even a tool for any activity requiring reliability and security. The developers are too busy coming up with new tricks to fix existing problems properly.
