In other words, the reader doesn't appear to be aware that the card was inserted. I can't tell why because your usbmon log didn't start at the beginning. In your testing you should issue the "cat 1u" command before plugging in the Myson device, and make sure the SDHC card is inserted before you attach the USB cable. You don't have to insert and remove the card several times; just wait a few seconds (until the "sde:" message appears in the system log) and then stop the test. Also, for comparison you should run the same test on the PClinuxOS system.
