![]() ![]() Something goes very wrong between the ConnectUSB.kext that Parallels loads, and the USBOverdrive.kext. Trying to solve the issue I discovered that USB Overdrive is to blame in my case at least.Īfter I removed it, no more problems! I even stressed the system to the point of 200.000 pageouts and no physical memory left free, with 3 Parallels VMs loaded, all Adobe CS3 suite, Safari, iTunes playing, and everything was working, slow but steady.Īfter I closed the programs everything returned back to normal, where with USB Overdrive installed the general chopinness remained, especially in the Dock, until I restarted my Mac. Or the Dynamic Pager of OS X not being able to assign virtual memory swapspace,Īnd iTunes stuttering when playing music at the same time Parallels is loaded. This includes general lags, the dock becoming unresponsive and the dock bouncing choppy, early pageouts for no apparent reason,Īnd messages in system log like: IOHIDSystem: postEvent LLEventQueue overflow, A little research on your BIOS version should make it clear to you whether upgrading your current BIOS will fix the problem.I have noticed a lot of slowdowns and weird behaviour with Parallels and OS X, especially under low free memory conditions. Upgrading the BIOS should be kept as a last resort and should only be performed by people who know what they are doing. Note: Please upgrade the BIOS at your own risk. You can read our articles on how to update the BIOS of an HP Desktop/Laptop, a Gateway Desktop/Laptop, a Lenovo machine, an MSI motherboard and of a Dell Desktop/Laptop. ![]() There was positive feedback from the users that updating their BIOS resolved the error message “USB Device over current status detected”. ![]() In modern computer systems, BIOS is stored in flash memory so it can be rewritten without the menace of replacing the hardware. Traditionally, BIOS was written on ROM and hardware needed to be replaced when updating the BIOS. Most of the BIOS are designed specifically to work with a specific model or motherboard. The BIOS is also responsible to test hardware components on your PC and make sure that they are working properly without any errors. Either you can replace it or get it checked by a technician. If it doesn’t, it means the USB socket was problematic. Now turn on your computer and see if the error message persists.Once you have located the pins and socket, unplug the connector.These USB connectors will most probably be for the front of the PC since the connections for the back of the PC are directly connected to the motherboard and you cannot do anything about them. Once you see the motherboard, search for USB connectors.Open your computer’s case from the side by unscrewing the nuts and bolts. Also, unplug the power cable from the socket. Damaged USB ports will indeed be responsible for the overflow and cause your computer to shut down. It is possible that the USB connectors present in your tower are not properly connected to the connecting pins or the USB ports are somewhat damaged. The next thing you should check is the USB connections present inside your tower/PC. If you cannot diagnose which device might be causing the error message, it usually means that there isn’t any problem with the USB devices. Solution 2: Checking Front USB Ports Connected
