m16 Posted September 4, 2008 Share Posted September 4, 2008 Hey I just bought a corsair memory stick and when I use it in my hackintosh under OSX it gets about 2 mb a second write speed usually lower... Under windows it is much higher... Whats wrong? In BIOS I have USB 2.0 enabled...

ameris_cyning Posted September 4, 2008 Share Posted September 4, 2008 What is the USB stick formatted to? NTFS, FAT? Link to comment https://www.insanelymac.com/forum/topic/124437-slow-usb-transfers/#findComment-879991 Share on other sites More sharing options...
m16 Posted September 5, 2008 Author Share Posted September 5, 2008 whatever the apple format is (trying to get time machine working but transfer speeds sooo slow) Link to comment https://www.insanelymac.com/forum/topic/124437-slow-usb-transfers/#findComment-880198 Share on other sites More sharing options...
ameris_cyning Posted September 5, 2008 Share Posted September 5, 2008 With the stick in, go into the System Profiler (Quickest way to get there is to click on the Apple menu --> About this Mac -->More Info button), and click on USB. Find your stick in the device list of the USB panel. What does the speed section say?

bazz38 Posted September 5, 2008 Share Posted September 5, 2008 I have exactly the same problem... Systemprofiler shows the following: USB-hogesnelheidsbus: Location hostcontroller: Expension slot Besturingsbestand hostcontroller: AppleUSBEHCI PCI-apparaatcode: 0x293a PCI-revisiecode: 0x0002 PCI-fabrikantcode: 0x8086 Busnummer: 0xfd USB Storage: Versie: 96.02 Busvoeding (mA): 500 Snelheid: Maximaal 480 Mb/sec Productcode: 0x070e Serienummer: 000000009602 Fabrikantcode: 0x05e3 Sorry, im Dutch, so all info is in Dutch too xD. But everything is like it should be.. I guess it has something to do with incompatible AppleUSBEHCI, maybe i'll try using some older versions of it. Running 10.5.4 now, nothing modified except audio & PS2 driver.

Gringo Vermelho Posted August 21, 2010 Share Posted August 21, 2010 Be careful, AppleHPET.kext is required for native speed stepping on compatible Intel hardware. If your USB ports are listed as being on an 'Expansion Slot' in System Profiler, you may be able to fix it in DSDT by following the instructions given here: http://www.insanelymac.com/forum/index.php?showtopic=168014 Link to comment https://www.insanelymac.com/forum/topic/124437-slow-usb-transfers/#findComment-1533981 Share on other sites More sharing options...
