I just got a generic USB hub (4 ports) as a gift from a company. There is no indication of the brand at all either on the hub itself or its box. I plugged it in my MacMini and nothing happens (which seems pretty normal) but then I tried to plug different types of USB devices (both USB1 and USB2 devices) in the hub and none is detected.
Cyberpower Laptop Driver For Mac. I hope this is the right place to put this thread. I can't figure out where this should go. Anyhow, I'm thinking of purchasing a custom-built PC from CyberPower PC. Has anyone here dealt with them? Before purchasing from them, I want to make sure they're a worthwhile company. I can't find many ratings for them. Cyberpower Pc Driver Update. The intel is nice yes, but you can save $100 and get a 2.5GHz and not notice. (unless you plan on running Unreal 3, Doom, Oblivion, Warcraft, and Halo at the same time) Whatever you do.DO NOT USE CYBERPOWER!!! They got shinny adds but you dont want the headache. Check whether the keys continue to function when the LED lights turn off. If they do not, the keyboard is likely losing power. This can be caused by a faulty connection between the USB cable and the keyboard.

I tried the hub on my Windows PC and it is immediately detected as a 'generic USB hub', and all USB devices work perfectly with it. I looked at the properties of the device in the Windows device manager, but there is still no indication of the type of chipset included (just 'generic usb hub').
Is there a way to scan usb ports under Mac OS X? Something like the lspci command under Linux which scans PCI devices and reports chipset types? I tried to look at various logs but I cannot find any trace of the hub or the devices I tried to plug in it.
First, when asking for help with a peripheral or peripherals, name the peripherals at issue. Next, Macs do not show empty drives and vacant ports. If you insert removable storage in a powered drive, then it will mount the storage volume. As for those other USB devices, they may be use bus power or require external power. Whatever the power source, it needs to be powered on to show up. Some devices are plug and play. Others require user-installed drivers to operate.
Printers and scanners fall into this category. Some of these require setup after the drivers are installed. Without a clue what your problematic peripheral(s) might be, there is nothing more that I can say.
My post probably wasn't clear enough, but my problem is precisely that I don't know exactly what type of USB hub it is, since there is no indication at all on the device and I received it without any kind of instructions. Though, I am asking if someone knows a command or software that could tell me which chipset is included in the hub, so I can try and find a driver somewhere. I tried to find some software to scan USB ports and report information on connected devices but couldn't find anything useful yet. My bad, I didn't understand you were talking about the devices I tried to plug into the hub.
Here is the list:. A 5-buttons Microsoft IntelliMouse Optical mouse, which is the mouse I currently use with my MiniMac. My standard 109-keys USB Apple keyboard.
An USB2 512 MB Verbatim memory stick (formatted as FAT). An USB1 generic (no brand) 32 MB memory stick (formatted as FAT) All these devices work without an external power supply and work perfectly when I plug them directly into the USB ports of my MacMini. However, when I plug them (one at a time) into the hub, the memory stick volumes are not mounted, the mouse cursor does not move and nothing happens when I press a key. Basically, it looks like the devices I plug into the hub are not even detected by the OS.
Mar 22, 2017 - I'd like to take a moment to clarify that this list is for apps that you can download onto your Mac. There are some great e-readers that are. Nov 8, 2014 - eBook Reader is an affordable digital book reader compatible with Intel Mac computers running Snow Leopard (OS 10.6) or later. Download ebook reader for mac os x.
I too thought that USB hub didn't need drivers as I thought they are basically the same kind of hardware that manage USB ports included in the MacMini for instance. Here, I believe the chipset included in this low-cost hub is not recognized by the system, which thus does not recognize to what kind of device it is talking to. When I use the system profiler (can't believe I didn't think of using it, I am too much of a Linux user still, I always try the command line to solve problems ), the hub simply does not appear in the hierarchy of USB periphericals. Thanks anyway for the help.

Common troubleshooting issues with the CyberPowerPC RGB 7 Color Keyboard.
The colored lights behind the keys are not lighting up like they are supposed to.
Check to make sure that the key is not stuck in place, and will return to its original position after pressed. If the key doesn’t appear to be sticking, there may be an issue within the circuitry of the keyboard itself. See the key repair guide for details: CyberPowerPC RGB 7 Color Key Replacement Replacement.
The colored lights are not turning on under the keyboard.
Plug the keyboard in and test to see whether the keys are functioning. If the keys aren’t working, the keyboard itself may not be receiving power through the USB connection. See the USB Outlet repair guide for detailed instructions on how to replace a non-functioning USB connection: CyberPowerPC RGB 7 Color USB Outlet Replacement.
Check to make sure that the key is not stuck in place from crumbs or debris. If not, check to make sure the key is not stuck in place, and will return to its original position after pressed. If the key doesn’t appear to be sticking, there may be an issue within the circuitry of the keyboard itself. See the key repair guide for details: CyberPowerPC RGB 7 Color Key Replacement Replacement.
If the keys are continuing to function while the backlight is off, it is possible that the LEDs themselves are damaged and need to be replaced. See the LED light repair guide for detailed steps on how to repair damaged LEDs: CyberPowerPC RGB 7 Color LED Backlight Replacement.
The colored lights are flickering.
See whether the lights flicker in response to the keyboard being shaken. If they do, this is likely an indication that a piece of wiring inside of the keyboard is loose. For a repair guide on how to replace faulty wiring, see the LED light repair guide: CyberPowerPC RGB 7 Color LED Backlight Replacement.
Check whether the keys continue to function when the LED lights turn off. If they do not, the keyboard is likely losing power. This can be caused by a faulty connection between the USB cable and the keyboard. See the USB Outlet repair guide for details on how to replace a faulty USB connection: CyberPowerPC RGB 7 Color USB Outlet Replacement.
The keys on the keyboard are not working when pressed.
Check whether the keys are visibly sticky or dirty, or whether there are crumbs or dirt in between the keys. In this case, the keys may need to be cleaned with compressed air in order to prevent dirt from interfering with the contacts between the keys and the circuit board.
Check whether the backlight is working. If neither the backlight nor the keyboard itself is functioning, the keyboard may not be receiving power through the USB connection. See the USB Outlet repair guide for detailed instructions on how to replace a non-functioning USB connection: CyberPowerPC RGB 7 Color USB Outlet Replacement.
The keyboard is not being detected by the computer when plugged into the USB outlet.
Check to make sure the cable is completely plugged into the current USB port. If this is not working, attempt to plug the keyboard into another USB port. If this solves the issue then the error is with the original USB port; if this does not solve the issue, there may be an error with the keyboard’s hardware.
