The problem lies in the incompatibility of Intels USB 3.0 drivers to 2.0 devices. Has anyone tried a USB 2.0 hub or even a 3.0 hub? I should grab one from work and experiment. Since the Intel drivers cant handle data like realtime high quality audio or video signals via USB cause of the limited bandwith and many bugs they still have the Intel driver causes the M14x R2 to bsod. The problems mainly occur if you are into music production, djing or just very audiophile so you need an external audio interface with better quality and outputs than the integrated sound chip. Sadly there is no fix at all the power saving settings has nothing to do with this issue i also deactivated the LPM settings for my SSD and other tools. Hi mw86 ofc its nice to have some representives from Alienware here. They are so ignorant following their down written standard text but to try to understand what the customers is even telling them.
They dont know much about their own products and ask you to reinstall windows or drivers again and again no matter what problem you told them youre having. We only get the useless uninstall this or try this answers that have nothing to do with the problem at all. Sad that we cant have the simple stuff working in the new system and it should be a shame for the Alienware team that they are not even trying to get it solved. The R1 is good then for older games and proffessional audio and video producing, djing and vjing. However this makes the R2 perfect for gaming only but not for proffessional audio or video producing or even djing. If Dell had integrated the Renesas Controller like in the M14x R1 there would be no problem at all cause i got a R1 and it works perfect. The power saving settings has nothing to do with this issue i also deactivated the LPM settings for my SSD and other tools.
Maybe it gets an upgrade in a later revision such as a Bus Controller that can handle the port issue.Īt the moment we can either use USB 3.0 speed or the USB 2.0 port not both together. Since Dell doesnt care for their customers it seems the M14x R2 stays broken portwise. Intel does not plan to fix their drivers as i could see in their errata non fix list for june and let the Notebook brands alone to solve this issue. The problem is Intel USB 3.0 driver doesnt work native when there are other non USB 3.0 ports and the Panther Point needs either fixed drivers or like the M18x an additional Bus Controller to manage all ports. And the M18x has an additional Bus Controller for the ports, the M14x R2 doesnt. Im sure Steven will be able to give more info on this but.
I know i have a device or so that hates those ports so ive been sticking with my usb2 ports unless i found i absolutly needed the usb 3 but honestly have avoided those prts like the plague since. I read if issues in my M18x and i know usb wont even function over those usb3 ports when the driver isnt installed.
Sorry again for kinda offtopic and congratz to your VBIOS mod svl7!
Since you guys are the most pro people i know and it must have something to do with the Dell BIOS A03 for the M14x R2 maybe you got a clue what could be the problem and why we M14x R2 owners cant use audio interfaces and usb hubs. This problem is not specific to my laptop, many other also have this problem that they cant use usb hubs or external audio interfaces. When i uninstall the driver everything works fine but i only have USB 2.0 speed on the 2 USB 3.0 ports and one unknown device which is the USB 3.0 controller in the device manager. Only a wireless desktop directly plugged in works when this USB 3.0 driver is installed. I recently got my M14x R2 and the "Intel USB 3.0 eXtensible Host Controller Driver" crashes my USB 2.0 so i get hangups, bsods and freezes when i plug in an audio interface or usb hub. Hi guys ! sorry for posting something nearly offtopic here but no one could help me anywhere else in the webs forumworld since its a pro problematic.
