Dear user "BradtheRad";
Finally I solved the problem using fujitsu.com website:
The solution is:
The Intel® USB 3.0 eXtensible Host Controller Driver is not supported in Microsoft® Windows XP or Microsoft® Windows Vista.
The USB 3.0 controller must be disabled in the BIOS when using MS Windows®...
Thanks for reply.
yes. I have tried "disabling and enabling" usb ports on device manager, but not yet tried " uninstalling and installing". I'll try it too. even in BIOS I have disabled and enabled all usb ports. but without any result.
now I'm going to check out your suggestion.

Hello everyone;
My laptop model is Fujitsu Lifebook E752 with two USB.2 ports and two USB.3 ports. I have windows XP and 7 on two different drives. A long time ago I locked and then unlocked my usb ports on windows XP by using locking/unlocking software. now I have problem with three ports of 4...
Hello every one;
I'm recently interested in learning ARM microcontroller and I'm a newbie in this field.
in order to experience memory addressing for this microcontroller I have written a program in KEIL uvision for AT91SAM7x256 chip.
after preprocessor instructions this is first line of my...
thanks for reply;
I guess I have explained my problem in wrong way.
I bought only ST7540 chip( with no waranty ) not ST7540 evaluation board and I'm sure my adapter output voltage is 12.5V with no ripples.
I just guess my chip failed because of leaving CL and Vsense pins floating while...
Hello every one;
I have bought a pair of ST7540 (Power Line carrier modem). I connected it to a host controller( AVR chip) and tried to read its internal register.
when I connected 12.5V supply to circuit, smoke rised from my ST7540 and fired!!!
after this, I checked out if my 12.5V sypply has...
tnx for your replies;
I have done all these you mentioned, but TL494 and LM339 are healthy.power transistors driver is healthy too. but yet nothing!!!!!!!
I've connected 2A load to +12 and Gnd but in this case, the slight 20 degree revolution of the fan disappears!!!!!!!! in addition with no...
Hello everybody;
I have a PC power supply in which when I connect Green wire to GND wire the power supply fan just turns for 20 degree and then stops.TL494 and rectifier diodes are healthy but I don't know how to remove the trouble of this power supply.further, +5V stand by is live too.what...
Re: Graduation project
Hello ever one;
I need an idea for my graduation project.my major is control and Instrumentation.I'm interested on Microcontroller control systems.does any one have any idea?
thanks.
thanks for your reply.
let's discusse more about ultrasonic technique.
I guess: By ultrasonic technique,used pipe material will be important.Further,the fluid viscosity will significantly be effective on output measured frequency or transit time.
I'm right?
how can I compensate these effects?
I want to measure liquid flow by a contactless clamp flow meter(It's my graduation project).in other words I should build a
cotactless clamp liquid flow measurement instrument.does any one have idea how can i do that?
I intended to measure it by electromagnetic technique but it needs two...
