Memory Card Reader on Linux

Memory Card Reader on Linux

A cheap USB connected memory card reader works out-of-the-box in Ubuntu Linux.

Using a no-name USB-connected memory card reader on Linux. Using this procedure, I succesfully read and wrote data to memory card on Linux. All required software and drivers came with Ubuntu default installation, without any additional drivers. Reading and writing a memory card is very fast, 128 MB takes about a minute.

  • Memory card: a tiny 128 MB TransFlash card (fingernail size, used on mobile phones)
  • Adapter: SanDisk SD TransFlash Adapter (bought with the memory)
  • Reader: “Card Reader Writer USB 2.0”, “22in1”, a no-name card reader sold in Clas Ohlson Helsinki for 22 EUR.
  • Linux: Ubuntu 5.10 Breezy

No other wires are needed. The device is automatically detected later when memory card is inserted. The driver disk is only for Windows, the reader works out of the box without any driver disks on Linux.

Copy files to and from the memory card by dragging files.


Before removing the memory card from the reader, it must me umounted (”unmounted”) from the system. Right click the memory card icon on desktop and choose “Unmount Volume”.

Despite umounting the memory card, the orange light is still lit. It does not seem to matter, the card can still be removed.

Remove the card from the reader.
