Thread: USB 3.0 - 10.5.8 - Universal

I wasn't sure where to put this - as I know that most of the forum deals with x86 applications - but I figured, heck this is hardware mod - if anyone know the systems its the users of this forum. I post part of this in the kext premium area as well - if anyone can solve it.

- Personwho helps solve this problems – will be mailed a USB 3.0 PCI Sonnet Card –

Card in Question: SonnetAllegro USB 3.0 PCIe

Problem: I have a Lacie USB 3.0 External HardDrive. I have a Power Macintosh G52.5 Ghz Quad Core Computer with several extra PCI Express slots. I purchased a USB 3.0 card slot hoping that it would be able to run on 10.5.8. Now I know the site says that it only supports 10.6 and later, but I chose this PCIe card for a special reason. After downloading the drivers from Lacie, CalDigit, etc. –the achieve extract of the content package was a .kext file that was Universal not Intel – this gave me hope that with some adjustment the PowerPC platform would be able to operate this PCIe card.

I attempted to modify several .kext files to make the card be recognized, but to no success. I see that the USB 3.0 card from Lacie has been patched by Modbin - but when installed on PowerPC it does not work. Though I do not have the exact Lacie 3.0 card the Sonnet uses the same chipset (maybe new revision though). If anyone has ideas about this problem / possible solutions the many PowerPC users who still have great last generation computers would appreciate it...we don't have a forum of our own. Thanks in advance for any input.

LaCie is the premier manufacturer of high quality digital storage.

Is your Mac ready for USB 3.0?
Mac Pro/MacBook Pro with OSX 10.4 or later
Other Any -Your Mac is not USB 3.0 compatible

I have to admit it is not very clear but the only supported Macs are Intel Macs.
So no PPC code.
It is not the card that gives the problem, it's the PPC code. There's no kext in PPC.

Somebody has to write a kext in PPC code, which I think would not happen. It's a hell of a job.

I knew the Universal Driver for the USB 3.0 card - wasn't hindering the problem. It will just be difficult now to get 10.5 the support it needs with PPC kext files to support the USB 3.0 card. Not impossible - just a little complicated. Thank you for the reply - I will keep my fingers crossed and hope I can track down a programmer who can add the support to the kext files for the card.
