Episode 1080

Torry from Floyd, VA

Torry has been a programmer since he was a kid and he has a bunch of 5 1/4" floppy discs with his original programs on it. Where can he get a USB drive that can read them? Leo says that at this point, eBay may be the best bet. But it's quite possible that he may not be able to get one that's USB powered. The challenge is going to be that it uses a serial interface and he'll have to have an adapter in order to get it to work.

Why won't my iPhone charge with a Lightning connector?

Episode 1061

Lou from San Diego, CA

Lou has an iPhone 5 and has been hesitating upgrading to iOS7, so he hasn't. Leo says that Apple will be releasing iOS 7.1 soon, so it may be wise to just wait a little bit longer. Lou also wants to know why the Lightning connector doesn't work all the time. Leo says that if Lou bought it from a third party, that could be the issue. If it's not charging, it may be that Lou is connecting to a USB port that doesn't have enough juice running through it. USB adapters have different amps. Anything less than 5v x 1 amp, it won't charge. The iPad requires 5.1 v x 2.1 amps.

Can I install a USB 3.0 card in my desktop using PCI?

Episode 1056

Dave from Chicago, IL

Dave wants to know if he can install a USB 3.0 port onto his desktop computer. Leo says sure, but it largely depends on the bus of his desktop. If he has PCIexpress, he should be just fine. USB 3.0 goes as high as 5 Gigabits, but that doesn't mean he'd necessarily get that. What about just plain PCI? He won't get the max speed, but the hard drive isn't as fast as USB 3.0 either. So it should be good enough for his use of it.

Is there a way to connect my Samsung Galaxy S4 to the car without having to use bluetooth?

Samsung Galaxy S4

Episode 997

Randy from Richmond, VA

Randy listens to TWiT podcasts with his Droid connected to his car dock, but his Samsung Galaxy S4 will not pass audio from the phone to the computer without bluetooth. Leo says that's odd that they've taken those features out. He suspects it's because of Bluetooth that they've taken it out via the USB port. An audio jack plugged into the dock could work, but he'll have an extra wire running.

Why do I get an error whenever I try programming my ham radio through my computer?

Episode 994

Gordon from Tarzana, CA

Gordon has a BaoFeng UV5R+ ham radio, and it keeps displaying an error whenever he tries programming the radio through Windows. Leo says that less expensive ham radios don't have an ideal user interface to allow the user to troubleshoot easily. Leo suspects that the USB cable is broken, but he also suggests making sure the drivers for Windows are installed first.

The Chatroom says it's the "prolific driver" that's causing the connection. They recommend using Chirp on Windows to find it.

Why does my keyboard type numbers and letters on its own?

Logitech Bluetooth Keyboard

Episode 984

Trish from Chino Hills, CA

Trish's keyboard seems to randomly type letters and numbers when she's not touching it. Leo suspects the keyboard could have shorted out or the USB port it's plugged into is shorting out. She should try a different keyboard. If that doesn't fix it, then that would point to a different problem. Leo also suspects that the computer may still be paired to the wireless keyboard and her daughter is playing with it, causing the issue!

Why won't my computer recognize the bootable USB key I created?

Episode 965

Robert from Newhall, CA

Robert wanted to create a bootable operating system on his USB key, but his computer won't recognize it. Leo says it may not be formatted properly. He should go into the BIOS and make sure USB is an option to boot to in the boot order. The Chatroom suggests holding down ALT+O when booting up and it'll tell the computer to look at the USB, but Leo hasn't done that so he can't vouch for it.
