Acer Aspire One D255E - continuing problems with card reader

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..

Re: Kernel 3.03 - keucr module defective
Fatdog64 already has the keucr module, but it may not support your particular device. Typemyke wrote: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
Code: Select all
cat /proc/bus/usb/devices
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.

Status of ENE Card Reader in kernel
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.

Possible workaround
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.
