All microUSB cables are not the same



This is a salutary warning to all geeks out there….even with all the year’s of experience, it’s still possible to make a rookie mistake and forget that all microUSB cables are not the same.

Last week at work, I needed to present an Android tablet screen via a data projector. The tablet only had a microUSB port, so connecting up directly via HDMI or VGA was out of the question. I’d have to mirror the tablet screen to a PC and then show the PC screen on the projector. WiFi wasn’t available to the PC, so it needed to be a wired connection but fortunately I had a drawer full of USB A to microUSB cables. I connected the Samsung Tab S2 to my PC and got on the with the job.

The wisdom of the Internet suggest that AirDroid was the one to try, so I signed up for an account, downloaded the PC software and installed the app on the tablet. Could I get the tablet to mirror to the PC? Not a chance!

Back onto the Internet, I then discovered that the Samsung tablets have an app for this called Flow, which doesn’t need rooting or developer access. Brilliant. I chucked AirDroid out the window, downloaded the complementary PC software….only to find that it’s for Windows 10, not Windows 7. This isn’t going well.

A bit more research and I further find that Flow’s predecessor is SideSync. There’s an app in Google Play, there’s a download for Windows 7…this is it, sorted….Nah, still doesn’t (expletive deleted) work.

I’ve been at this for hours and at this point I start to blame ActiveDirectory policies but it’s time to go home so I take the S2 home (leaving the USB cable) to see if I can get it to work on my personal laptop. And of course, it works straightaway.

At this point, the penny drops. It’s the bleeping USB cable. The one at work is a “charge only” cable whereas at home I’ve a proper “sync’n’charge” cable.  I’ve wasted half a day because I forgot that not all microUSB cables are the same. Back in work the next day, it’s time for lessons learned and I get the scissors out. Useless pieces of junk.

To paraphrase a European politician, there’s a special place in hell for companies that bundle charge-only cables with their products to save a few pennies.

And Samsung’s SideSync did the job perfectly. Thumbs up!
