Hi, You can download the driver here then : www.driverslab.com/drivers/MP3/iRiver/15/56.html
www.givemefile.net > ... > Audio player > MP3 Flash-player
Kind regards, Jay

you just uninstall that unkown device which you get in device manager and reconnect the pendrive if again it says unknown device then goto update driver and select 2nd option which is advanced in that select don't search for driver i'll select and select the driver which is shown in the list and click next and finish ur pendrive will works

Go to your control panel open up 'administrative tools' Open Computer management, then choose disc management instead of device manager. Make sure that you have the drives pluged in and connected before you do that. All connected drives formatted or not that are in working order should show up under disc management. If they are not showing up they are not compatable. Make sure that they are marked as active and format them if they need to be formatted. Do so by right clicking on the drive in the disc management window.

OK, this problem was driving me almost to tears with frustration but have managed to bodge-solve it so hope this helps!

Right click My computer and select Properties.
Click on Hardware tab.
Click on Device Manager.
Hopefully there is a yellow question mark symbol against Iriver T30 listed under other devices or portable devices or something.
Right click this then select Update Driver.
Tell it that you are going to manually update the driver yourself.
Eventually you will have to select what type of device it is - select portable device.
Now click on MTP device and click next to install the driver.
Hopefully now it is recognised by XP in My Computer....

Good luck

First make sure you have the right drivers installed, you're hearing the "new device connected" sound when you plug it in, it's listed as recognized under device manager, and the only problem seems to be that iriver music manager isn't recognizing it.

If everything is working except for the music manager, then try holding down the "fast-forward" button at the same time that you connect the cable to the iriver. You probably want to keep iriver music manager loaded, to see if it's recognizing the player while you test this; try attaching/detaching the device several times, while you're holding down fast-forward and while you aren't, to see if that's enough to fix your problem.

I have no idea why it works when it does, it's an ugly kludge, but it seemed to fix the problem for me, and saved me from having to buy an entirely new flash mp3 player to replace this ancient one.

Try plugging in usb with the H10 turned off. Now, press the select button (with the round symbol on it) while turning the H10 on. This starts the player in 'emergency mode' and should be recognized by XP

THE FOLLOWING IS COURTESY OF MICROSOFT Help and Support

When you plug a USB device into a Windows XP-based computer immediately after the computer comes out of standby (S3) or hibernate (S4), the computer may not recognize the USB device. When this issue occurs, the USB device may be listed in Device Manager as an unknown device, and you may receive the following warning message:
Unrecognized device has been found.

This issue occurs because, when the computer comes out of S3 or S4, there is a five- to ten-second period when the selective suspend feature of the USB driver will interfere with detection of a new USB device connection. The time period depends on several factors. This includes the following factors:• Host controller hardware
• Attached hubs
• Attached devices
• USB driver versions
• Support for USB 2.0
• Additional system hardware or configurations that may change the timing
There may be other reasons that a USB device is not detected

Method 1
loadTOCNode(2, 'workaround'); After the computer comes out of S3 or S4, wait five to ten seconds before you plug the USB device into the computer or hub.

Method 2
After the computer comes out of S3 or S4, unplug the USB device, and then plug the device back into the computer or hub.

Method 3
Use the Device Manager to scan for new hardware. Follow these steps: 1. Click Start, click Run, type Devmgmt.msc, and then click OK..
2. On the Action menu, click Scan for hardware changes. This causes Windows to recognize new devices.
3. Close Device Manager and Control Panel.

Method 4

Note If you perform the following procedure, you may also reduce the battery life on a portable computer.
To disable power management on the USB hub, follow these steps: 1. Click Start, click Run, type devmgmt.msc, and then click OK.

Try restarting the computer with the device in. Sometimes if you clear the memory that might help (stating the machine without memory then put it back and start it again).
