[ubuntu] Lenovo laptop SD card reader not working

The adapters are designed to sit completely flush with the curved bezel of the systems, so as to be, for all practical purposes, integral parts of the machine. However, they are also completely standard ExpressCard adapters and can work in any machine with an ExpressCard slot.

Several different revisions of the adapters were made, with different FRUs, and probably different underlying controllers. The one I obtained originally supplemented the Ts series. Thus, ballpark expected performance is known for it as well, but will there be any surprises? This is bad for normal operation, as it drains the battery faster, but for the tests it was fine. This is the first device that is not a uPD adapter where I encountered this problem, so at this point I am more inclined to believe that the L0s interoperability problem lies with the Intel chipset, or the Lenovo BIOS, rather than the endpoint devices.

Again, I did not have time to investigate it Lenovo ThinkPad T430s Realtek Card Reader depth — maybe in the future.

This is a core component of the OS, and as such a different version is used in each OS version. Note that the XP indicates version 6. I could not successfully test all scenarios with this driver; For the X built-in card slot, both Win7 and Win8.

The Ts exhibited the same behavior for the 04W under Win10 x64, and there it was even impossible to fully uninstall the Ricoh driver, as it Lenovo ThinkPad T430s Realtek Card Reader to be inbox and keeps reinstalling itself. Strangely, the 04W adapter, which appears to be the same hardware, had no problem running either with the Ricoh or with the Microsoft driver, only in the X More interesting are the performance differences.

The XP results are very surprising. I ran the test several times to makes sure it was not an error, and the results were consistent.

I do not have an explanation for this. Note that the same Ricoh driver version was used in XP and Win7, but one is bit and one is bit.

Either something in the XP subsystem is more efficient than in later OSes, or something in the bit Ricoh driver is more efficient than in the bit one. Since at the moment, I have neither bit Win7 installations, nor bit XP installations, I cannot check it at this time.


I only tested the system briefly, so I will compare the results of the RTSA to the best result I had with each of the faster controllers. Device System Read seq.

Read 4K Write 4K. Got an issue with my card reader, bit weird, upgraded to Windows 8 from Windows 7, all worked fine before.

When I insert a SD card, Win8 recognises it ok and opens the folder on the card. This is where the problem is.

I go into Device Manager and everything is ok. I have to restart the laptop for it to clear.

Then its fine for one time again. I un-installed the Realtek drivers and let the Microsoft generic drivers kick in.


My laptop is an Acer z running windows 8 64bit. All was working when running windows 7 64bit So, as we can see, Realtek seems to be the culprit, and I have researched more on this subject and, indeed, found more Windows 8.
