Please contact the manufacturer of your computer. • Does your computer meet the USB specifications? If you are using a computer that does not fulfill the electrical requirements of the USB specifications, operation may be unstable. In this case, you may be able to solve the problem by connecting a USB hub. If the above actions do not solve the problem, it is possible that the PCR-30/50 has been incorrectly detected by the computer. As described in “” (p. 89), delete the incorrect device information, then re-install the driver. (.“Setup” (p. 13)) Troubleshooting “Found unknown device” appears even though you installed thedriver If your computer or USB hub has two or more USB connectors, and you connect the PCR-30/50 to a USB connector to which the PCR-30/50 has never been connected before, the “Unknown device” dialog box may appear even on a computer onto which you have already installed the driver. Refer to “Setup” (p. 13), and install the driver once again. This is not a malfunction. If the "Found unknown device" dialog box appears even though the PCR-30/50 is connected to the same USB connector as before, it is possible that the computer has detected the PCR-30/50 incorrectly. As described in “” (p. 89), delete the incorrect device information, then re-install the driver. (.“Setup” (p. 13)) An “Unknown driver found” dialog box appears, and you are unable to install the driver Device Manager shows “?”, “!”, or “USB Composite Device” Driver is not installed correctly It is possible that the computer has detected the PCR-30/50 incorrectly. 1. Turn off the power of your computer, and start up Windows with all USB cables disconnected (except for keyboard and mouse). 2. After Windows restarts, use a USB cable to connect the PCR-30/50 to your computer. 3. Turn on the power of PCR-30/50. 4. Click the Windows [Start] button, and from the menu that appears, choose Settings | Control Panel. 5. Double-click the System icon. The System Properties dialog box will appear. 6. Click the Device Manager tab. In Windows XP, select the System Properties Hardware tab, and click Device Manager. 7. Check whether “EDIROL PCR” with an “!” or “?” symbol is displayed below “Other Devices”, “Sound, Video, and Game Controllers”, or “Universal Serial Bus Controller”. If you find any such indication, select it and click [Delete]. 8. A dialog box will ask you to confirm deletion of the device. Verify the contents of the dialog box, and then click [OK]. In the same way, delete all occurrences of “EDIROL PCR” that have an “!” or “?” symbol. 9. Check whether “Composite USB Device”, “USB Device”, or “USB Composite Device” with an “!” or “?” symbol is displayed below “Other Devices”, “Sound, Video, and Game Controllers”, or “Universal Serial Bus Controller”. If you find any such indication, you need to determine whether it has appeared because the PCR-30/50 has been detected incorrectly, or because there is a problem with some other device. To determine this, switch off the power of the PCR-30/50. If the “Composite USB Device” (or other) indication disappears when you turn off the power of the PCR-30/50, then it is the PCR-30/50 that has been incorrectly detected. Return to step 2 Troubleshooting and continue the procedure, and when you reach step 8, delete the information that was detected incorrectly. If the indication does not disappear when you turn off the power of the PCR-30/50, then this indication refers to a different device. Do not delete it. “Composite USB Device”, “USB Device”, or “USB Compatible Device” may sometimes indicate a device other than the PCR-30/50. Be careful not to accidentally delete the registration for another device. If you delete the registration for another device, you will have to reinstall the driver for that device. 10. A dialog box will ask you to confirm deletion of the device. Verify the contents of the dialog box, and click [OK]. Delete each unwanted occurrence of “Composite USB Device”, “USB Device”, or “USB composite device” indications with an “!” or “?” symbol. 11. Turn off the power of the PCR-30/50, then delete the driver. “Deleting the driver” (p. 91). 12. Restart Windows. Then install the driver once again. (.“Setup” (p. 13)) * If the problem still occurs after you have taken the above measures, please refer also to the Readme file for the USB driver. The Readme file is on the CD-ROM.
