Resumen del manual
Use the following procedure to check whether the USB interface is enabled. 1. Click the Windows Start button, and choose Control panel from Settings. In Control panel, double-click the System icon. 2. Click the Device Manager tab, and make sure that there are no yellow “!” marks or red “x” marks displayed beside Universal serial bus controller or the USB Root Hub below it. If a yellow “!” mark or red “x” mark is displayed, the USB is currently disabled. Refer to the owner’s manual for your computer, and enable the USB. Has an Unknown Device been registered? > If while installing the UM-2 Driver, installation is halted for some problem such as a cable being pulled out, the UM-2 will be registered as an Unknown Device, and it may be impossible to perform the installation again. If this occurs, use the following procedure to Remove the Unknown Device, and install the driver once again. 1. Click the Windows Start button, and choose Control panel from Settings. In Control panel, double-click the System icon. 2. Click the Device Manager tab, and with View devices by type selected, make sure that there is no Other devices. If there is, double-click it, and if there are any Unknown Devices below it, click to select them and then click the Remove button to Remove them. 3. Disconnect the USB cable from the UM-2, and then re-connect the cable. If the computer recognizes the UM-2, perform the driver installation from the beginning. Troubleshooting Is a Roland USB-compatible product other than the UM-2 connected to your computer? > If the UM-2 Driver is installed when a Roland USB-compatible device (UA-100 etc.) is connected to your computer, the UM-2 Driver may not be installed correctly. If you wish to simultaneously use both the UM-2 and another Roland USB-compatible device (such as the UA-100) on the same computer, you must disconnect the other USB-compatible device from the USB connector before installing the UM-2 Driver. Case 2: USB connections cannot be made correctly Has the UM-2 been recognized? > Disconnect the USB cables, and then re-connect them. > It is possible that the computer has failed to recognize or initialize the UM-2. Leave the USB cable connected to the UM-2, and restart Windows. If connection still does not occur, exit Windows, and turn off the power of your computer. Then turn on the power of your computer and start Windows. Are your computer or USB hub (*) supplying sufficient current? > If insufficient current is being supplied to the UM-2, connection is not possible. • Use a USB hub which contains its own power supply. • The power conservation mode settings of your computer may be limiting the current supplied to the USB, so check these settings. What is USB hub? A “USB hub” is a device that expands the number of USB connectors. Broadly speaking, there are two types of USB hubs. Self-powered hubs (USB hubs containing a power supply): The USB hub itself has an AC adapter, which supplies power (normally 500 mA) to the added USB connectors. Bus-powered hubs (USB hubs not containing a power supply): The hub does not contain a power supply. The power supply of the connected computer is re-distributed to the added USB connectors. For details on the electrical current that can be supplied by your computer or USB hub refer to the owner’s manual for your equipment. If you have questions, please contact the manufacturer or dealer for your computer or USB hub. The UM-2 cannot be used with a hub that contains no power supply. When a USB device is connected to a computer, the USB device tells the computer how much electrical current it uses. If this value exceeds the current that the computer is able to provide (maximum 500 mA), the device cannot be connected. The UM-2 will request 120 mA of current when it is connected to a computer. Most computers or self-powered USB hubs will have no problem with this current capacity. If you are using a dual-mode USB hub (self-powered / bus-powered), be sure to connect its power supply (AC adapter etc.) and use it as a self-powered USB hub. Troubleshooting Case 3: Cannot shift to Suspend (*) Is an application which uses the UM-2 running? > Exit the application which is using the UM-2. The computer cannot shift to Suspend mode if an application such as a sequencer is using the UM-2. What is Suspend? This is a function which minimizes power consumption by shutting down the internal circuitry of the computer and the peripheral devices while the power remains supplied to the computer. Case 4: UM-2 does not resume correctly from the suspended state When suspended, was the UM-2 still connected via the USB cable? > Disconnect the USB cable, and then re-connect it. On some computers when Windows resumes from the suspended state, the UM-2 may fail to resume. If this occurs, the USB cable connected to the UM-2 should be disconnected and then reconnected. Case 5: Windows hangs up (freezes) when returning from the suspended state > Disconnect the UM-2’s USB cable before sus...
