    Featured Functions Connect Automatically for Printing This is another one of our very convenient functions. What this function does it that when you send a printing task to this printer, it detects this printing task and AUTOMATICALLY connect this printer to print out the document. When the printing task is done, the printer will then be AUTOMATICALLY disconnected so that other users can use it.

  • Page 24: Automatic Connection

    Automatic Connection There two ways to automatically connects USB devices: automatic connection by device and automatic connection by USB port. Automatic Connection by Device Once enabled, THIS PARTICULAR DEVICE will be automatically connected when: The software starts up and the device is online and Free. The software is running and the device comes online.
  • Page 25 Automatic Connection by USB Port When this function is enabled for the port, the USB devices will be automatically connected when: The device is plugged into the port when the software is running. The device is plugged into the port and is Free when the software starts up.
  • Page 26 Also, like automatic connection by device function, if the user disconnects the device manually, it will NOT be automatically connected again until the software has been restarted. Create a Shortcut on Your Desktop This function creates a shortcut on your Desktop that, when double clicked, starts up an application and connects a targeted device at the same time.
  • Page 27 However, this shortcut function consolidates these steps into two quick double-click. Let’s see a sample use case. Take this EPSON MFP as an example...
  • Page 28 Right click on it and select the “Create a Shortcut on Your Desktop” option.
  • Page 29 Then you will see this setup dialog pops up. So, this EPSON MFP comes with a scanning application called EPSON Scan. You can see a shortcut of this EPSON Scan software being placed on your Desktop. Now you can either Drag-and-Drop the EPSON Scan shortcut into the highlighted text filed.

  • Page 32 Then you will see a new shortcut being created on the Desktop. The naming rule of the new shortcut is adding a “Network” prefix to the name of the original shortcut.
  • Page 33 Now, when you double click the new “Network EPSON Scan” shortcut, the software runs and the EPSON MFP gets connected at the same time. You can then start your scanning task.
  • Page 34 When you are finished, simply close the EPSON Scan utility and the EPSON MFP will be disconnected automatically. Now you can operate your MFP or Scanner with a shortcut on your Desktop and keep the USB Server software minimized at the system tray.
  • Page 35 Auto Disconnect Printer/MFP/Storage Device These functions are there to prevent the case when one user connected a Printer or Storage device but forget to disconnect when he/she is done with the device.
  • Page 36 When these two functions are enabled, you will see this message when you connect a Storage device or a printer:...
  • Page 37 When the Idle time is up and the device has been disconnected, you get another notification: NOTE: This function might not work with Storage device such as pen driver/flash driver. These devices tend to periodically (on a millisecond base) communicate with the OS even when the user is not reading data from it or writing data to it.

Request Disconnect Device: When you want to use a device occupied by other user, you can highlight that device and use this function. This sends a message to the occupying user with your request. The occupying user would either release the device or deny the request if s/he is still using the device.
  • Page 44 Search When you are in need of knowing the status of all the servers and devices immediately, use the Search button. Clicking on the Search button triggers the program to immediately poll the network for the status of all the servers and devices. The result will be updated to the tree view.
  • Page 45 View The tree view in the main dialog has two display modes: “Servers and Devices” mode and “Devices Only” mode. The default setting is “Devices Only” mode. You can toggle between these two display modes with the View option on the control menu:...

Once you have seen the bug happen again, you can use the Extract log file function to extract the file and send the file in for analysis.
  • Page 49 Extract Log File Clicking on this option brings up the folder where the log file is kept.
  • Page 50 FAQs General Questions Q. How come I don’t see any device on the utility? Besides the obvious reason that your PC or the USB Server might not be connected to the network correctly and or the product is not powered- on, using a personal firewall on your PC might block the program from accessing the network.
  • Page 51 Q. How come I can’t see any USB device on the USB Server GUI? First of all, of course, check and if your USB device has been correctly connected to the product and powered on. Another possible reason is that, even though the USB server does support USB hub, the combination of a Full Speed Hub with a Low Speed Device (such as mouse, keyboard, etc), is NOT supported by this product.
  • Page 52 Q. How come I don’t see the USB hub on the utility? By the product’s design, USB hub is not considered as a USB device in the common sense. The reason for this design is that, connecting to the USB Hub is quite meaningless since it provides no meaningful function as connecting the device behind the USB hub would, hence we simply do not show USB hub on the utility.
  • Page 53 Q. How many USB printers can I connect to this product? Depending on the product design, you should be able to connect at least one and up to four USB printers. Please consult the supported device list for all the supported printers. Q.
  • Page 54 Q. Does this product support USB web cam? This product supports only one USB web cam. Many web cams on the market today are what we called USB 2.0 device. USB 2.0 devices, by specification, could be transmitting data at 480 Mbps during operation. The bandwidth provided by this USB Server product is at most 320 Mbps.
