USB Ethernet stop working after 10.7.5 update

After updated to 10.7.5, my usb ethernet stop working, and always shows it doesn't connect.
Reinstall 10.7.5 make no difference.
How do I solve it?
Thanks!

Or download it directly from ASIX Electronics instead of driversworld.us.

I installed it and my AppleUSBEthernet started to work.
The error i had (sudo dmesg):

USB Ethernet stop working after hotplug

I have found that my Apple USB Ethernet dongle stop working if I plug in another USB device. This happens both using a USB hub, and when plugging directly into the MacBook Air. I also see this problem when using a similar dongle from another supplier (called AX88x72A). The USB Ethernet dongle works fine after booting, with status "Connected", but if I plug in another device like my phone or a USB drive, the status changes to "Cable Unplugged" after a few seconds, ifconfig no longer show the en1 interface, and syslog gives a few error lines such as:
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: en1
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: Ethernet \[AppleUSBEthernet\]: Link down on en1
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
After this, I must reboot the MacBook Air to get the dongle working again. Do anybody know how to force the AppleUSBEthernet driver to rescan the device tree (or something similar)?
With regards,

I have exactly the same problem here (MacBook Air 2,1 - OSX 10.6.8). After several tries (and reboots!), I've found that an unload/reload of the USB Ethernet driver works.
Note that operation is not automatic: I have to execute commands in a terminal in order to retrieve my Ethernet connection... but it is far better than a reboot!
So, if you want to test my method, once you have plugged a USB key (or after an hotplug of your USB-ethernet dongle), you can execute these commands on your terminal (note there are 2 lines and no space in the kext name, a space may be inserted by this forum):
sudo kextunload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
sudo kextload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
Of course, i've made a small script with these commands, and copied it on my PATH so it is even easier to execute it. It works perfectly for me, and I hope it could help.

HP Pavilion dv6 All 4 USB ports stopped working

Hello,
I recently bought a Pavilion dv6-6c11sa laptop. Windows 7 Home Premium 64-bit
Everything was working fine for about a week, and then yesterday all of the USB ports stopped working. I have 4 USB ports in total, two 2.0 and two 3.0. No matter what peripheral device I plug in, mouse or flash drive etc, they're not recognized by the laptop. The lights don't even light up on the devices, regardless of the port. I've tried uninstalling and reinstalling the drivers in device manager, taking out the battery and rebooting, installing the chipset drivers (AMD), nothing works. No programs had been installed 3 days prior to the occurence, although I had rebooted several times in that time frame. I simply booted up the laptop yesterday, and nothing worked.
Could anyone offer a solution or suggestion, please?

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. WHen we plugged it into the port on the keyboard, the device works. Why?

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. When we plugged it into the port on the keyboard, the device works. Why? Obviously the device is operational. Could the USB port have burned out from having too much power drawn? If so, is it reparable?

It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired.

Will Apple's USB-Ethernet Adapter Work on iMac

One of the pins in the ethernet port of my iMac were bent. The second I attempted to bring the pin up, it broke. So I haven't been able to use ethernet for over a year.
Will the Apple USB Ethernet Adapter work on my Late 2006 2Ghz Intel Core 2 Duo iMac? It is loaded with Leopard 10.5.5. I've read these adapters would only work for MBAir but will it work on my iMac?
I'm not looking to get back Gigabyte Ethernet capability, I generally want to use ethernet again.

I do have a Base Station the current base station.
All my stuff except my iMac & iBook is packed deep in a storage facility since I'm on a move to someplace else. Meanwhile I'm staying in a place that doesn't have Wi-FI but offers wired ethernet connection.
I have my iBook but I want to use my iMac again & that adapter is all I need to get it connected. I just want to know if it would work since it's intent is for the MacBook Air.

USB Video stopped working with 3.1.8 update

I have been using iChat video with my USB camera for a while with the help of iChatUSBCam. The new update of iChat (3.1.8) included support for USB cameras and once installed my USB camera stopped working with iChat. It just reports the camera is in use by another application. I've been browsing for answers for a while and have tried many things:
- Restart in various combinations of unplugging and plugging in the camera
- Reinstalled the Macam driver
- Reinstalled Quicktime
- Uninstalled iChatUSBCam (since iChat is supposed to work without it now - I think...)
- Reinstalled iChatUSBCam (v 2.2.1 - current)
It's a Logitech Quickcam for Notebooks Deluxe. It continues to work fine with Skype and the the Macam camera tool. I'm using Skype for now (on tour for 6 weeks and use it to video call home) but the quality is crap compared to what iChat used to do.
Thanks for any help you can give.

Some people have reported that Updating iChatUSBCam
and deleting the Macam drivers and then the
com.apple.ichat.plist is the way to go.
Thanks for your help!! I tried these things before, but tried them again in the order you suggested with no success. I'm pretty sure it is not a UVC compliant camera. It's not on Logitech's list of UVC cameras.

If I try it without the Macam drivers it doesn't show up as a camera is connected at all.
It's so frustrating because it was working great with iChatUSBCam until the recent update. It still works in Skype with no problems, but I'd rather be using iChat if I can - much better video quality.
Thanks for any suggestions!

1 of 2 USB ports stopped working after 10.7.2 upgrade

I have the newest Macbook Pro. I upgraded to 10.7.2 today and immediately after, 1 of my 2 usb ports stopped working.   Thought it may be the cable, so I switched cables. Tried plugging in my iPhone, my portable drive and nothing.   Both work on the other port though.   Both ports worked fine before the update.
I've rebooted 4x.
Suggestions?

One usb port stopped working today

One of my USB ports stopped working today. I think it may be related to Itunes update today. Has anyone else seen this recently? I restarted my computer - but that didn't help. I have a MacBook Pro - running Lion 10.7.5
Any suggestions? I saw one USB Hub when I went to Apple --> About this Mac, but couldn't tell if both were there.

USB ports stopped working in my Macbook Pro

USB ports stopped working in my Macbook Pro

I do not know anything about audio consoles nor do I have an iPhone.
My iPod also does not show on the desktop but it is recognized in iTunes, Check if that is the case for your MBP.
Do you have the appropriate boxes checked in Finder Preferences?
See if this support article is of any assistance:
http://support.apple.com/kb/TS1410
If you have an external HDD, connect it to your MBP and see if it is recognized. If it does not show on the desktop, check Disk Utility.
Have you tried all USB ports? It could be that the problem lies in your MBP.
Ciao.

Ethernet stopped working suddenly

I've been reading various topics on this board and it seems like many people have this problem but there are not many solutions.
My problem is that my ethernet stopped working suddenly. I've taken the following steps:
- reset the cable modem
- reset the router
- turned off my ethernet card and rebooted the computer then turned it on again; renew DHCP ip
- create a new location
Does anyone have any suggestions?

I'm not an expert, but here are a few suggestions & questions:
• Did you reset things in the order you wrote them in your post i.e. modem before router? (That can be important. Also I find it takes my modem a couple of minutes to establish a connection, so I wait for a while before I turn on the router.)
• Do you have any other computers wired up? Do they work?
• Have you tried setting the computer location to Automatic?
• Does your Modem have LED readouts which indicate when it is connected to the Internet and to a router?
