Connecting Edirol UA-25 Interface to iMac

hi all. i just bought an iMac and successfully installed the Edirol UA-25 software. However, when i restart the iMac after installation and plug in the interface, my mac doesn't recognize it...nor does the interface turn on. i tried finding it when searching in the sound utilities and it wasn't available in that drop-down list either. what else can i do? i tried re-installing the software and it confirms that installation is successful...so, i don't really know what to do next. (i'm admittedly new to this.) any help would be greatly appreciated.

iMac, Mac OS X (10.5.7)

Did you download the newest driver or use one supplied on a cd?

If the interface won't turn on then the mac wont be able to see it. Are you using a usb port on the imac the imacs keyboard or a hub?

i'm using the disc supplied with UA-25 and the USB port. i'll see if i need to an updated driver, but it probably isn't likely, right?

Hi,

as far as i know, the Edirol has a switch on it's back to select between standard and advanced drivers. Standard should work with Core Audio Standard (without drivers), but to use "Advanced" you need the newest Roland driver.

The buzzing can have other causes. Please make shure you put your speaker's power cord into the same power outlet source as your iMac and (if it has) the edirol power connector. Check if none of the cables is lying beneath a power cable, transformer or whatever could induce humming.

But: If the problem persists, and you just bought the Edirol, turn it back to the dealer - it may be a defect (this may happen even with edirol 😉 )
