Further investigation with all the debugging output enabled shows that it’s the ‘test unit ready’ command (0x0) that fails: --8<---------------cut here---------------start------------->8--- COMMAND phase dir 0 lun 0 cmdlen 12 cmd 0065c1c4 datalen 0 pdata 0065c478 cmd[0] 0x0 cmd[1] 0x0 cmd[2] 0x0 cmd[3] 0x0 cmd[4] 0x0 cmd[5] 0x0 cmd[6] 0x0 cmd[7] 0x0 cmd[8] 0x0 cmd[9] 0x0 cmd[10] 0x0 cmd[11] 0x0 STATUS phase ptr[0] 0x55 ptr[1] 0x53 ptr[2] 0x42 ptr[3] 0x53 ptr[4] 0x7e ptr[5] 0x0 ptr[6] 0x0 ptr[7] 0x0 ptr[8] 0x0 ptr[9] 0x0 ptr[10] 0x0 ptr[11] 0x0 ptr[12] 0x1 FAILED COMMAND phase dir 1 lun 0 cmdlen 12 cmd 0065c1c4 datalen 18 pdata 0065c1d4 cmd[0] 0x3 cmd[1] 0x0 cmd[2] 0x0 cmd[3] 0x0 cmd[4] 0x12 cmd[5] 0x0 cmd[6] 0x0 cmd[7] 0x0 cmd[8] 0x0 cmd[9] 0x0 cmd[10] 0x0 cmd[11] 0x0 DATA phase pdata[0] 0x70 pdata[1] 0x0 pdata[2] 0x2 pdata[3] 0x0 pdata[4] 0x0 pdata[5] 0x0 pdata[6] 0x0 pdata[7] 0xa pdata[8] 0x0 pdata[9] 0x0 pdata[10] 0x0 pdata[11] 0x0 pdata[12] 0x3a pdata[13] 0x0 pdata[14] 0x0 pdata[15] 0x0 pdata[16] 0x0 pdata[17] 0x0 STATUS phase ptr[0] 0x55 ptr[1] 0x53 ptr[2] 0x42 ptr[3] 0x53 ptr[4] 0x7f ptr[5] 0x0 ptr[6] 0x0 ptr[7] 0x0 ptr[8] 0x0 ptr[9] 0x0 ptr[10] 0x0 ptr[11] 0x0 ptr[12] 0x0 Request Sense returned 02 3A 00 --8<---------------cut here---------------end--------------->8--- The request sense KCQ can be interpreted as ‘Not Ready - Medium Not Present’, according to <https://secure.wikimedia.org/wikipedia/en/wiki/KCQ>, despite the fact that the SD card is actually in (and Linux can successfully read from it.) The card reader has USB IDs 05e3:0726 (Genesys Logic). Any idea how to go further? Besides, ‘usb_request_sense’ and ‘usb_test_unit_ready’ both assume LUN == 0. Could it be a problem?
