Need to Watch Video on Laptop Via USB Port?

You've kind of answered this yourself - you need a USB or PCMIA video capture card, which will probably come with some software which will let you record the images on the hard drive. If you do this, you will not be able to plug the RCA into its 'normal' socket and unlike audio you cannot 'split' the signal with a 'Y'plug. Cheers

1. Windows 7 x64 RTM USB Port Has Power But Won't Recognize Mouse/Keyboard/Anything

Here's the pro and easy fix for future people with the same problem:Disconnect your computer from any and all power sources (so for towers, turn off and unplug your power source, for laptops, turn off, unplug, and take out your battery for a good 30 seconds)Your USB port devices should be working properly now. Flipping usb microprocessors right?

Short and simple answer "NO" the battery charged by via a charger which the USB cord is only used to downloading photos onto the computer

4. IS THERE A USB PORT IN OR OUTSIDE MY BUTT FOR CHARGING MY PHONE?

5. how do i get photos from a digital camera??

You can either plug the USB cable into your camera and into your computers usb port and go to my computer and click on the camera icon. Then copy and paste all the photos onto your computer. You then can burn them to a cd if you wish. You can also take the memory card out of the camera and go to your local camera/photographic shop or newsagent/chemist which have digital printing services. Another option is to order prints over the internet.

6. HELP! My laptop heats up fast and easily!?

Never use a lap top on soft surface like pillows, bed, sofa blocks the cooling vents. Blow out the cooling vents with canned compressed air made for cleaning computers. Buy and use a lap top cooling pad with built in fans and connects to USB port for added cooling. Lap tops get very hot on bottom to touch this is normal because of the compactness of the components and lack of air space.

7. What is the power output of a USB port?

As stated in WikipediaThe USB 1.x and 2.0 specifications provide a 5 V supply on a single wire to power connected USB devices.A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2. 0; 6 (900 mA) in USB 3. 0. As power is equal to current times voltage, all you have to do is multiply 5V with the current the device is drawing from the port.Note there also exists a convention for charging devices. These kinds of ports allow for currents up to 1. 5 A (also using 5V). However, the USB port is rated to withstand current up to 5 A--so some manufacturers may go out of spec and offer a higher maximum current

8. can a female A USB port be used on an OTG host?

Yes, the standard Type-A receptacle is still a standard way to have the USB host design. However, the industry is moving towards Type-C connectors. The Type-C may look over-complicated at first, but you can elect to use a minimal Type-C configuration (USB2. 0 only, CC pins 56k pullup) to provide the basic host functionality, yet to be fully USB compliant. But if you do want to use OTG functionality (as per question clarification), it is not possible to accomplish this with Type-A receptacle, because the A-connector does not have the necessary ID pin to switch the function. The OTG port has only two physical data wires, D, and D-. The bus CANNOT BE DEVICE AND HOST SIMULTANEOUSLY! It either one, or another. Inside your MCU there are two different logical functions/controllers, a host controller, and a device controller. They SHARE a single USB PHY, by means of internal multiplexer of two different data paths. However, you can put two USB connectors, Type-B receptacle, and type-A receptacle, connect D/D- electrically in parallel, but use the VBUS from B-connector as OTG switch signal. This will constitute an ugly kluge, it contradicts every USB specification, and it will cause massive user confusion

Macbook Pro Early 2011 Model Motherboard Short Circuted on Connecting Data Cable to USB Port
I youtubed/googled the issue and all I needed to do was remove the battery plug on the logicboard and I guess the system resets and it worked again. MacBook Pro alive.How did I learn this? This happened to me at well. I had my MacBook Pro 17' connected to my Thunderbolt Display and when decided to charge my ipad using the USB and when I connected the iPad, everything shutdown. I couldn't even power it back on. Took it to apple store and they told me 500 bucks. WHAT$$$ They don't even diagnose the problemI have macbook pro early 2011 MC700 model. Few days back I was using it on battery and connected my samsung phone data cable to USB port and when I was about to connect other end of cable to my phone, macbook crashed. I took it to service centre and after few days technician told me macbook motherboard has short circuted and it need to be replaced. My macbook is just 3 month old and warranty has saved me from the cost of repair. I want to know what exactly is reason of short circuit. Is it fault in that model or this kind of short circuit of motherboard on connecting data cable is a common phenomenon. Now in future I will think twice before connecting my USB cable or pendrive to USB port of macbook. What can be exact reason of shortcircuit of motherboard. Thanks in advance.Regards,Anuj·OTHER ANSWER:I have macbook pro early 2011 MC700 model.
