Description: This is an awesome little microSD card USB reader. Your uSD card slides into the inside of the USB connector, then stick this into a USB port and the card's contents will pop up on your computer. Very sneaky - we love it! Great for pulling data logs off microSD media. This reader also includes an indicator LED which will light up if a microSD card is present. This device is completely plug-and-play, no drivers needed.

Why is microSD sometimes called 'uSD'? It's an engineering thing. Mu ('μ') is a Greek letter that is often used in engineering. In electrical engineering it is commonly used to shorten capacitor sizes, such as 10μF. This is pronounced '10 micro-Farad'. Using that same terminology, we can shorten microSD to μSD, but we're just too lazy to figure out how to type μ, so instead we use 'uSD'.

Features:

  • TF/microSD/microSDHC card high-speed reader
  • USB interface
  • Supports up to 32GB capacity cards
  • Supports Windows (98, ME, 2000, XP, Vista, 7) and Mac (9.0 and above) OS's

  • Nice little card & the price is right!
    First, a quick clarification: the card enters the USB side of the dongle (the metal side). This makes sure that the card cannot fall out when it is plugged in to a computer. The plastic side has a little slot (visible in the pics above) that you put your fingernail in to eject the card. The only drawback is that you can’t connect the MicroSD sniffer because it is too long.
    Here’s the device info:

  • I’m so ordering one of these! :D

  • Would this perhaps work with an OTG device, thinking that I might use this and this to expand the storage to my Nexus 7.

  • Can anyone confirm that this module is hot swappable? Can I keep the module plugged in and swap out micro cards without unplugging/replugging the module first?

    • The micro sd card plugs in the metal usb side, so no, I don’t see how that would be possible.

    • I have owned a few that are, but just got this one and it is not. Like the LED, the plastic cover that comes with it, the little hole to tie a leash and even the somewhat backwards way to plug in the card (it keeps the card safe and secure with the plastic cap on and stored.)

  • I ordered one of these someplace but mine came with a cover for the metal connector part when not in use.
    Does this one come with that cover and it is just not shown or did I buy it someplace else ?
    I liked the one I have and wanted a few more but can’t remember where I bought it.

  • With a large MicroSD card, this would make for a decent covert storage unit.

    • The description says it only supports up to 32GB cards, and it (obviously!) doesn’t support MicroSDXC cards. uSDHC cards that this reader recognizes only go up to 32 gigs anyway.

  • i actually have a tiny 4 GB USB flash that looks just like this, but the plastic broke off, revealing that there was a microSD 4GB in there. I’m surprised this thing costs $7 without any microSD in it, because the one i have cost me only $11 with the 4GB uSD in it. A word of advice, since this thing is so tiny, it is sometimes difficult to unplug it from the USB port, and you sometimes have to pry it out with your fingernails. Be careful, though! That is how mine broke off!

  • anyone know if/how far the Tflash card pokes out of this thing or is it flush with the reader when inserted. i’m thinking of grabbing one of these for my head-unit in my car for playing mp3s off of and i want something that is going to be as unobtrusive as possible when plugged in.

  • Hello All
    I did try the Silicon Motion Site and left an email looking for a data sheet, I could not find this device posted there…. The Micro card reader came in the mail today. On the package is listed www.kawau.com.cn The site is in Chinese, It is a model C266 I can find photos all over the place, but no data sheets, any ideas???? I bought this to program the micro card for the SOMO-14D Audio Sound Module.
    Thanks

  • Do you know the IC used by this device?
    Does it have Linux support?

    • I haven’t had any luck getting this to work in either Arch or Ubuntu. The following are the relevant dmesg entries I get after plugging it in:
      [377892.152110] usb 3-1: new full speed USB device using uhci_hcd and address 18

      I haven’t had a chance to try this on a windows machine, so I suppose it is possible that I got a DOA.

  • How fast is it?
    Like, with a standard Kingston or Sandisk card?
