Mac OSX 10.10 and DWM-221 (4G LTE USB Adapter - D-Link)

Hello,

I have a usb modem 4G LTE from DLINK.

The model is DWM-221. After upgrading my system to OSX YOSEMITE, the connection software can't find the modem on the USB port.

On Mavericks everything was perfect.

Exploring the CLARO (Carrier) installation bundle, I have the kext files. I already copied those files to /system/library/extensions, but it didn't work.

Any one is having the same issue? Any ideas to how fix this problem?

MacBook Pro with Retina display, OS X Yosemite (10.10), USB MODEM LTE 4G DWM-221

I've found a new pack of drivers released by D-LINK and now my Macbook Air 11 is working fine.

Click on the following link (http://www.dlink.com.br/sites/default/files/product_download/dwm-221_claro_patch _mac_10_10_v1.pdf) and you will find the directions to fix this issue (instructions are in PT-BR).

One additional step not mentioned in the link above: after finishing the steps mentioned, Shutdown your Mac, remove the modem, Turn it On again, insert the Modem in the USB port and start D-Link Connection Manager.

Cheers,

Leo

Hi,

When I saw your post I thought DLink (or Claro) had finally released a proper device driver for Yosemite and later!

But, the "patch" is an executable that adds to the machine boot configuration the same settings I had suggested in my post.

To confirm that is the case, before running their "patch" (in a machine never configured to developer mode - I disabled dev mode in mine before doing this) try:

ideiafix:~ andre$ nvram -p

backlight-level %ae%01

BootCampProcessorPstates %0b%00

bluetoothInternalControllerInfo %89%82%ac%05%00%003%14%80%e6P%0d%9b%a1

Then, execute their patch and execute the command again:

ideiafix:~ andre$ nvram -p

backlight-level %ae%01

BootCampProcessorPstates %0b%00

boot-args kext-dev-mode=1 <--------- HERE!

bluetoothInternalControllerInfo %89%82%ac%05%00%003%14%80%e6P%0d%9b%a1

Well, the same hack I was using... Shame on Claro (and/or DLINK) for not providing a real solution, coming with this horrible hack and worst, try to hide it from their clients...
