Hi Satya Thank you for your kind response. Please note that I ensured the connection of the USB upstream cable (as per my original post the USB connections on the BOTTOM of the monitor work fine, it's just the side panel that seems to be non-functional). Macbook os x lion. I have also tested the side USB ports with various devices that do not require higher electric current, such as USB sticks, a mouse, a keyboard, even an iPhone charger (my phone does not charge from either of the two ports on the side, but once again, it works fine from the bottom port). I also tested the card reader with various SD cards with no success whatsoever. Can you please advise? Kind regards Zoltan.

Hi Chris, Thank you for the informative (if somewhat blunt) response, in accordance to the aforementioned post I shall test the monitor on Windows 7 and if I experience the same, I will simply arrange a replacement with Amazon until they get it right (in desperate hope that I do not have to deal with your atrocious customer service ever again). Remarkable little saga about a lousy card reader, reminds me of a colleague of mine who has just decided against an Alienware gaming laptop due to atrocious pre-sale support - gosh, I don't know what I was expecting. I wonder if LG has an actual support for their monitors, if so it will definitely be worth the £100 extra. Kindest regards, Zoltan. Autocad mac os.

Hi Chris, Thank you, much appreciated. Here is where I am at: I bootcamped into a Win7 on the same Macbook, installed the latest driver (64 bit as per the OS), and the bottom USBs are still the only ones working. Moreover I have since had a system update on the OSX and the image has disappeared to reveal a message: 'There is no signal coming from your computer'.

I have a 3 mnth old Macbook, running OS X and Win XP (via Bootcamp). My problem is that in OS-X neither of my 2 usb compact flash card readers is recognised consistently. I have a couple of Kingston cards, a Sandisk Ultra II and a no-name. When I insert either of the Kingstons, both readers are usually, but not always, recognised. With the Sandisk and no-name, neither is ever recognised. Both readers and all cards are detected with no problem in XP.

It's something of a nuisance, because I'm going to be using the Macbook to back up photos on a holiday soon and had planned on deleting the XP partition to free up hard drive space. This is my first Mac and frankly I'm pretty surprised that plugging in a card reader, which I take for granted in Windows, is causing problems in OS-X.

Suggestions for a remedy welcome. -- Michael Kilpatrick. First - does anything else plugged into the same port work? (I've missed the obvious before) Second - have you tried rerinserting the reader?

Finally, open System Profiler (Applications -> Utilities). On the left side - click on USB. The right window will display a tree outline of all USB devices. You can click on any device to read info about the device in the bottom window.

Plug in your readerin any port. If it does not show up, under the View menu select Refresh (or use command-r) to see if it shows up.

I've had similar problems with my Sandisk reader & this usually resolves it. When ever I can't seem to find a disk that I know I have plugged in I always check the cable first to see if it is indeed plugged into the RIGHT port.

Then I use Disk Utility to verifiy the disk if is shows up. Sometimes I can't seem to see a hard drive USB or Firewire 400/800 that I KNOW is plugged in. The Disk Utility verify bump always seems to work to get it to show up on the desktop and finder. I too have had a few bad CF card readers as well as a LEXAR reader that did not like Macs and would not work. -- Tedd Greenwald reptiles native orchids and yacht photography. Thanks for all these responses. I'll give them a shot and report back.

Unfortunately, the option of buying 5 or 6 card readers, trying them until I find one that works and returning the others is generally not available here in Australia where I live. Retailers will usually only accept returns if the item doesn't work, not because the customer has changed his/her mind.
