I need a 1.1 USB cable for an alesis multimix 8 usb. Is the following an option for this; A 10- foot USB 2.0 cable with male to male connections / Connects USB 2.0 (or USB 1.0/1.1) peripheral to USB-enabled computer

A blown fuse will not produce smoke. A component failed and probably fried a resistor, which would smoke. That in turn would blow the fuse.Just replacing the fuse will not cure the problem. Your unit needs repair.

There are several possible solutions for this. The cheapest and easiest is to do the following:
Solution 1:
1. Get an RCA stereo plug to 3.5 mm plug. This will go from your mixer to your computer. This will not be the highest quality, but will work.
2. Get an XLR cable of the length you need. I would guess a standard one with a male connection on one end and a female on the other. Connect this to your powered speaker. Also, this is a guess as you didn't include the type of powered speaker, so I can't tell you for sure which cable to use.
Solution 2:
1. An alternate idea for better sound quality would be to run a D/A converter similar to this one: http://www.sweetwater.com/store/detail/USBMix/It would give you a much higher sound quality for everything. You would run from your Gemini to this. From this device, you would run a USB cable to your computer, and a 1/4" cable to your powered speaker.

Sounds like the output cable from the 802 is not correctly pinned to your input on the computer. Fred is on the right track but you may need to take it a bit further.
It may also be helpful to use a Pro USB audio interface such as the Digigram UAX220v2 (line level version).
If you wish to use the computer's on board sound card consider an IHF/Pro interface that converts balanced audio to unbalanced , and the proper cables. Two 3-wire balanced 1/4-inch from the 802 to the left and right inputs of the interface (XLR Male), then RCA (Red and White) to a 1/8-inch TRS Plug cable onto the the computers audio input.
Henry Engineering's Matchbox HD comes to mind.
Good Luck.

there may be maybe 2 a causes like it has a cut board or just the 7 segment fails!and need to replace a new one 7 segment

MIDI would be slower and would depend on the software and drivers as far as it working. Just have the USB jack replaced. Jacks are not very expensive.

Since this unit uses so little power, I would recommend a small stepdown transformer. A 20 or more Watt one is sufficient. DO NOT use a convertor that is intended for appliances like hair driers.

Here is a link... the smallest would work and costs $8... I don't know how they can make them for that. You might consider getting a bigger one if you get other equipment to run as well.

Finding the special power adapter that uses 220 and is compatible to the Alesis would cost much more.

What is the source of the input signals? These need to be balanced lines and the sources need to be balanced. If you happen to be using condenser mics, you probably haven't turned on the Phantom Power in the mixer. If you are recording from a sound card in the PC, those have a lot of noise and are unbalanced and you have to use DI's with ground lift ahead of this mixer.

You have to reduce the gain control for the input that clips (keeps the red peak iluminated). I suppose that the audio device that you connect at this input is connected at the line input (6,3mm jack) if it's a line level one, or at mic input (XLR 3 pin connector) if it's a microphone level one. You can clarify the gain controls from this picture:

What you need is 2 unlatched switches 1 for the stop start function and one for the drum fill function.
