- Power_LED - turned on after power-on during POST / USB initialization
- Access_LED - turned on after card is inserted and blinkig during card activity like read/write
Tested with 16GB Samsung microSD card with microSD to SD adapter
MX-18.2_x64 Linux (default, sysvinit boot):
1. if I insert 16 GB Samsung microSD into USB multi-card reader - nothing happens
2. after issuing in terminal "sudo partprobe" command, change is detected and I can browse card contents/files in Thunar file manager
3. if I eject / unmount card in Thunar - card is unmounted
4. after physically ejecting card from the reader Access_LED is turned off
5. after physically inserting card into the reader Access_LED is turned on and nothing happens
6. after issuing in terminal "sudo partprobe" command, change is detected and I can browse card contents/files in Thunar file manager
7. there is "MX USB Unmounter" on the panel - his behaviour is weird / wrong - card here is presented as 17G Volume ... " (why 17G? - card iserted has 16021192704 bytes)
8. if I double click to unmount on "USB_SD_Reader 17G Volume label_here" - "MX USB Unmounter" is killing power to USB card reader (Power_LED and Access_LED are turned off) - kernel says "usb 1-5: USB disconnect, device number 2" so I suppose that instead of card unmounting whole device is ejected. After this, ejecting/inserting card and issuing "sudo partrobe" nothing changes because card reader is 'dead'.
MX-18.2_x64 Linux (systemd boot):
1. if I insert 16 GB Samsung microSD into USB multi-card reader - change is detected and I can browse card contents/files in Thunar file manager
2. if I eject / unmount card in Thunar - card is unmounted
3. if I insert 16 GB Samsung microSD into USB multi-card reader - change is detected and I can browse card contents/files in Thunar file manager
4. if I double click to unmount on "USB_SD_Reader 17G Volume label_here" - "MX USB Unmounter" is killing power to USB card reader (Power_LED and Access_LED are turned off) - kernel says "usb 1-5: USB disconnect, device number 2" - like earlier (sysvinit boot) whole device is disconnected
Apart from USB flash-card reader disconnecting, "MX USB Unmounter" is not showing CD/DVD device with disc inserted during boot - if I click eject icon in Thunar or eject button on device itself and after this I close tray (with optical disc), CD/DVD reader appears in "MX USB Unmounter".
