Dawnsboy, Success! It worked. I would like to thank you very much for persevering in compiling this module. Between the two sources, the tools are now available to compile and use this module for kernels up to 2.6.38.

Once again, the Puppy Community (in particular, dawnsboy, pesamu, jamesbond and jemimah) have come through in helping a user!

Thanks again,

myke

I did not have to reboot after installing this package.
I simply inserted an SD card into the reader and it was detected...

Thank you, worked immediately after install.

I am glad that it worked. Thanks for the feedback.

Just installed keucr_2.6.33.2-lupu525.pet on an MSI U135 netbook running LuPu-525 booted from a USB flash card, actually an SD card in a USB reader.
Works perfectly, thanks a lot Dawnsboy!

Will also install it on a triple-boot Aspire One D255 (SPup-100, LuPu-525, Win7) on which the SPup-100 version is already installed & working.

Good work to get the JMicron cardreader working! Although only SD cards are mounted, unfortunately not xD nor Sony Memory Stick

I found a possible solution and driver source to fix it for xD/MS cards. I'm a n00b in buiding new PETs. Anybody here who can build it for Lupu 525?

thanks a lot tempestuous!
Pmount can't mount a MS. In my case it shows up as 'mspblk0p1' I added a line to /etc/fstab to have a quick workaround:

Code: Select all

/dev/mspblk0p1 /mnt/mspblk0p1 vfat rw,exec 0 0

and make a desktop shortcut to /mnt/mspblk0p1

Just for the record, Three Headed Dog is based on a later kernel, and it works just fine with the card reader in the Acer Aspire One. But I'm glad to find the pet for Lupu 5.25.

I would like to report that with kernel 3.03 in both 32 bit or 64 biot versions that the keucr module does not work and my SD card is not recognized..

Fatdog64 already has the keucr module, but it may not support your particular device. Type

Code: Select all

cat /proc/bus/usb/devices

and see if you can find the Vendor/Product ID codes for your card reader.

I need to test this too

I have a D255 that I never use due to the Fan too noisy.
but sooner or later the hdd in my D250 will give up and then
I will have to use the extra reserve having another almost identical.

so I need to learn these pets that help it work or to install those
puppy that do work with the SD cards. So thanks for providing them.

FWIW - I did a fresh install of lupu 528 (on Acer One) and keucr_2.6.33.2-lupu525.pet works with it.

After some googling and my own experiences, I found the following:

Kernel------->puppy------>module-->version------->status-->notes
2.6.33.2----->lupu 5.25->keucr.ko-->old source--->works-->pet
2.6.34.1----->spup-100->keucr.ko-->new version->works-->pet
2.6.35.7----->lupu 5.28->keucr.ko-->new version->works-->pet
2.6.35.7----->fatdog64-511->"------->new version->works-->gz file
2.6.38.8----->none------->keucr.ko-->" "-------->??----->rpm
2.6.39------->none------->ums-eneub6250.ko------>broken->no fix
3.0.1-------->same as 2.6.39
3.0.3--------> " " "

What happened is that keucr.ko was removed from the kernel as of version 2.6.39 and replaced with ums-eneub6250.ko, which does not work.

I suspect that dependencies or the structure also changed so that recompiling keucr.ko for later kernels would not work.

The bottom line is that the only way to use the card reader with the new puppies is to replace the kernel with a kernel in an iso that works.

Thanks that was very important information.
I have such computer so need to know what works and what not.

Myke. Thanks of your clarification. I have noticed your presented problem.
If you will find or read about working solution with these newer kernels, I am willing to help you with solution. Like compiling some third party kernel module and include it to the distro.

I don't have the expertise to do this, but it might be worth a try for someone who does...

Re: Linux 3.0: broken ums_eneub6250

Hi,

obviously, nobody seems to be interested to work on this bug. Until it's
fixed: There is a workaround to get the device working again with 2.6.39
and 3.0 - just remove the unusable ums-eneub6250.ko and replace it with
the complete old and fine keucr-module - staging but working

I am too lazy to test it but such info is very important
and much appreciated by us who owns that hardware.

I have both a D250 and one D255E. I only use the first
due to very high fan noise in the newer one having a more
demanding CPU needing bigger fan or higher speed or something.

It is much more noisy and I hate such noise. Sorry offtopic.

anyway it is good to know that one can use the card reader
when one really want to.

snowshaker · #50 Post by **snowshaker** » Mon 27 May 2013, 21:56

FYI - I have an Acer Aspire One ZG5 running Puppy 5.5, earlier than the D250, I loaded the PET and while it did not see the card reader initially, it did after a reboot.

Many thanks, dawnsboy.
