Nec Usb Open Host Controller Drivers For Mac

Premium SP1 with RENESAS-USB3-Host-Driver-21281-setup problematic

Anything from 1 to 10 re-installations of USB 3.0 driver required for connection to take effect

Once achieved, connection is solid, can backup etc BUT lost on restart

Windows 8 Consumer Preview

with Renesas USB 3.0 eXtensible Host Controller - 0096 (Microsoft) This driver is Native to WIN 8, when uninstalled , RE-installed automatically with 'Scan for Hardware Changes' or Restart

Anything from 0 to 6 re-installations of USB 3.0 driver required for connection to take effect

Once achieved, connection is solid, can backup etc BUT lost on restart

OBJECT:

Demonstrate that problem lies with WIN 7 / WIN 8 - Once connected, that lets your Host Controller and USB 3.0 drivers off the hook

METHOD:

A.

Use USB 2.0 - Until the Windows 7 team get their fingers out, time lost trying to make USB 3.0 work better used with that (slower) Backup.

B:

For those who want USB 3.0 to work and have the thrill of faster Access/BackUp

1. TOOLS: (USB 3.0 Host Controller PCI/PCI-e in your machine)

USB 3.0 Extention Cable (NOT 2.0) for ease of access(!)

USB 3.0 HDD External Drive AND/OR Flashdrive- USB 3 AND/OR USB 2**

** Host Controller and Ext. Cable can also handle USB 2.0, USB 1.1 - Part of WIN 7 weirdness

is when connected, on occasion, USB 2.0 Flash Drive NOT recognised (although connection sound, LED made) - Problem Not experienced with WIN 8 - Solution: Re-install driver

2.(a)

INSTALL USB 3.0 Host Conroller Software/Drivers (see list below) IF WIN 8 - not ness.

PLUG IN USB 3.0 Extension Cable (Otherwise you'll be on your knees, many,many times - unless it's a Laptop)

(b) PLUG IN USB 3.0 OR USB 2.0 FlashDrive - LED flashing, staying On, b-boing on speakers? - Good - Autoplay Window up? (might not be enabled) so check My Computer - Drive shown as 'Removable Drive'? - SUCCESS

3.

ROUTINE for Multiple Attempts to coax WIN 7 into USB 3.00 connectivity

a. Start/Control Panel/Hardware&Sound then OPEN Device Manager (leave open)

b. Expand - Universal Serial Bus Controllers - (near or bottom)

Locate - Renesas Electronics USB 3.0 Host Controller - (Ignore Root Hub)

Right click - select - Uninstall - Ok (If you tick box for delete driver, you'll need to re-install drivers)

REMOVE Flash Drive and/or Ext. HDD

c. Device Manager - Action (pull down menu) - Click on 'Update Driver Software..' / 'Scan for Hardware Changes'

What you want to see: [installing Device Driver Software] (Not shown WIN8)

Then: [Your Device is ready to Use]

Sis 7001 Pci To Usb Open Host Controller

Good,

but no guarranty of success - failure message? Repeat Step 3.(b)

PLUG IN Flash Drive and/or Ext. HDD - Connection? (see 2.(b))

IF NOT - REPEAT Step 3. (As many times as you can bear, my limit - 10 times per session) ( 6 times for WIN 8)

Software/Drivers tried on this Platform:

USB3.0_allOS_2.1.28.1_PV

OPINION:

This is a controversial topic, only in the sense that searches reveal many users with this problem and apparent silence from Microsoft (not slagging off, I am a fan)

For Example:

http://answers.microsoft.com/en-us/Search/Search?SearchTerm=usb+3.0&CurrentScope.ForumName=Windows&CurrentScope.Filter=windows_7&askingquestion=true Microsoft Answers yields zilch for 'USB 3.0' search

The fact that Microsoft are now collaborating with Renesas (was NEC) on WIN 8 Native

Renesas USB 3.0 eXtensible Host Controller - 0096 driver means that it should work and

any solution applied to WIN 7.

This cannot be a priority for Microsoft, only gentle pressure from users might help.

PROBLEM: Some Installations with WIN 7 don't encounter USB 3.0 bug, so:

BLAME: MOTHERBOARD / BIOS [Old PC after all] OR

Host Conroller Hardware Card / Firmware OR

Host Conroller Software/Drivers OR

Nec Pci To Usb Open Host Controller

OPERATING SYSTEM (o/s)

MY ARGUMENT and Simple Logic is:

IF USB 3.0 works flawlessly with WINDOWS XP

THEN Installations of WIN 7 and WIN 8 on the same Platform (Same Hardware),

Hi-speed Usb Host Controller

which exhibit no other problems and are perfeclly stable, should work.

Once connection is established, USB 3.0 works flawlessly - no breaks or drops

There are enough clues above, for someone knowledgable to push the envelope along,

Putting it simply, WIN 7 / 8 are 'weak' in STARTING process even though Device Manager reports 'This device is working properly.'

It might reside at the Boot/Logon stage

Another thought, IF all was well with these newer O/S's they should be

reporting error codes in Device Manager for USB 3.0 Host Controller

Clue: WIN 7 uses more than one version of:

What Is A Host Controller

USB Mass Storage Device (Driver Date & Version) {randomly?}

One is: 21/06/2006 6.1.7600 16385

others: 6.1.7601 17514

6.1.7601 17577 There may be more, but not found

any advantage with any particular one re: 'start_up' Glitch

For those who care - WIN 8 example is:

21/06/2006 6.2.8250.0 and XP 01/07/2001 5.1.2600.0

Possible clue:

WIN 8 came up with this error in Device Manager (USB Mass Sorage Device)

- 'Port Reset Failed' - when Flashdrive plugged in on BOOT/LOGON

That's all folks

PS. What ever you do, don't mention the CHIPSET, I mentioned it once but i think i got away with it...

Shortly after installing VMWare Player 3.0.1.11056 on my Windows 7 64-bit Dell E6400, I started having intermittent (90% of time) trouble getting access to my AT&T wireless PCMCIA card after resuming from Sleep/Standby. I've had this laptop since October and use Sleep mode a couple of times a day -- I never had this issue at all until I installed VMWare Player.

After much time spent trying to identify and solve the problem, I was finally able to find in the Device Manager thattwo deivices called 'NEC PCI to USB Open Host Controller' will have an error with 'Code 38' whenever this problem occurs. Sometimes sleeping and waking again will clear it, but usually not and a reboot will always clear the problem. I also found the event logs will have corresponding event IDs 219 for usbohci devices when resuming from sleep. The drivers are Microsoft drivers and can't be rolled back since the driver version has not changed.

Are there any solutions to this other than uninstalling VMWare completely and using another product?
