|Feedback on Possible Driver Sources for NEC USB 2.0 Chip in MDD G4 1.25/1.42GHz Macs|
|(Updated with more reader replies)|
Note: Two readers with G4s without the NEC USB 2.0 chip (a Dual 1GHz MDD model and a PB G4 17) both reported major problems after installing the OM USB 2.0 drivers and rebooting. As noted before, only the MDD dual 1.25/1.42GHz are reported to have the NEC USB 2.0 chip, but no feedback on anyone with one of those macs (yet) that has tried any of the USB 2.0 drivers. Here's one of the emails from a MDD dual 1GHz that tried the Orange Micro USB 2.0 drivers (without a USB 2.0 card or chip in the system)
"I just installed the Orange USB 2 drivers on my MDD Dual 1.0 (which doesn't have the NEC USB 2.0 chip) G4 running 10.2.5 (I don't have a USB 2.0 card installed, btw). I download the drivers fresh from Orange's website.
Oh boy! After restarting, it did not like those two .kext files added to my system. Instead of the normal dark gray Apple on a light gray background, I got a dark gray "no" symbol (a circle with a slash through it). And my machine would not startup. It wouldn't even power down.. I had to unplug the power from the back!
I had to reboot from another drive and remove those kernel extensions for my machine to return to normal!
I don't know if the same thing would happen with a dual 1.25/1.42GHz MDD model but just posting as a FYI/warning. (And of course Apple doesn't support any USB 2.0 drivers with the MDD G4 systems, so this is all experimentation to anyone that tries them.) Update: A Dual 1.25GHz MDD owner noted the same problem in Thursday's news - so these drivers are not compatible (not sure if there's some ID/edits that would help but just a warning to MDD owners using the standard installs).
In reply to the earlier comments from a Smartdisk USB 2.0 card owner that noted it had an NEC chip (but later said it was a 720100 not the 720101 chip on the MDD 1.25/1.42GHz macs).
SmartDisk does have their USB 2.0 drivers available, but it seems it is an
older version of Orange Micro's driver--dated April of 2002. People may be
better off using OM's newest 3.1 driver--dated several days ago.
But just in case, they can get it from SmartDisk at
Not sure if this driver would work but if anyone with a 1.25/1.42GHz MDD G4 tries it let me know.
Another reader replied to the earlier comments on OM USB 2.0 drivers:
just fyi, Orange Micro OEMs their driver, so if you buy an USB2 Mac card, it is very likely to have their drivers included. They use the vendor number (and I think item number) as a copy protection - you could easily update to a later version, as they include all licensed cards inside their driver.
This reader sent a link to some "generic" USB 2.0 drivers for OS X but no idea what chipsets they would work with. (The USB 2.0/10.2 driver link has "orange" in the filename so it may be the Orange Micro drivers v3.0 - not the later OM v3.1 drivers mentioned earlier today)
There are some more generic USB 2 drivers on this page
(earlier news item from this morning follows)
Two readers replied to the post in yesterday's news regarding the MDD G4 1.25 and 1.42GHz towers having an NEC PD720101 USB 2.0 chip, but no Mac USB 2.0 drivers listed at the linked NEC page.
I saw the article on the NEC PD720101 chip for the USB2.0 on the new
MDD Macs. I recently purchased a SmartDisk USB2.0/Firewire card and
they included a USB2.0 driver for the NEC chip on the card. I
installed the driver on 10.2.5 and all three USB locations work but I
don't have a USB2.0 device to test it out with. I went to SmartDisk's
website but they don't offer a download. It seems the only way to get
this is off the CD. I'm not sure about the legality of posting this
but if it helps someone out in the mean time all the better.
(I asked Don if he could check the NEC chip part number on the card)
I checked the card and the chip is an NEC D720100AGM. (the MDD photo showed a PD720101) I just did a
quick look over the datasheets for both the 100A and the 101. The
difference looks to be the voltage and system clock but I don't have a
lot of time to get into the specifics right now. There is a
significant difference in pin counts among the two chips which might
cause a problem. Here is the link to the 100A.
Another reader wrote regarding drivers for OrangeMicro's USB 2.0 card as a possible candidate:
"Mike, I read the posting you had about the new G4s having the NEC USB 2.0 Chipset
on them but needing drivers to enable USB 2.0 support. The OrangeMicro EHCI
http://www.macupdate.com/info.php/id/6403) support at least one of
the NEC chipsets. I have an IOGear GUF220 that has a NEC chipset for the
USB 2.0 portion but there is a sticker covering it so I can't get the part
number off the chip. It is most likely the PD720100 version though, and not
the PD720101 that is on the Apple Motherboards. However, OrangeMicro did
just update the EHCI drivers to 3.1, which might have added support for the
PD720101 chip. It would be really interesting to see if someone who has one
of the new motherboards installed the OrangeMicro drivers to see if the USB
2.0 support would be enabled. An IORegistryExplorer (part of the Developer
Toolkit from Apple) dump of the chip might help in identifying how the chip
is identified and if the OrangeMicro drivers will (or could be modified to)
Thanks -Chris D."
If any MDD G4 1.25/1.42GHz owner tries these drivers with a USB 2.0 device let me know if the work (for USB 2.0 rates - USB 1.1 is a 12Mbit/1.5MB sec max interface, USB 2.0 is 480Mbit/60MB/sec max interface) - although both are theoretical max rates which you won't see in real world use, however if USB 2.0 is enabled the rates with a USB 2.0 device should be much higher than USB 1.1.

If you've added a IDE, SCSI, Firewire or USB hard drive, CDRW, tape drive, etc. make sure you add a report to the database. (If you post an updated entry - make sure you use the same name, etc. as you did before so I can find your past entry. Thanks.)
(Incomplete entries are deleted. Do not post questions in the database, it's for drive reports not questions on what drive to buy - for that try searching the database for reports from owners of your mac model on the drive type/brand/interface, etc. you're interested in.)
