Boot problems with Belkin USB hub

I can boot to my internal drive with the Belkin 7-port hub connected. But I can't boot to the System Start-Up Disk or to my external with the hub connected. And once I try, I can no longer boot to the internal until I disconnect the Belkin hub.
I have heard their may be hub problems with the MBP and also with the Belkin hub. Any insight would be appreciated.

These are interesting problems. I have a Belkin hub and have been having long boot times (sometimes 5 or 6 minutes) with a blank blue screen for most of the time. I get partial relief by disonnecting the hub. I also have an SD card reader attached to the hub (Memorex brand), so I'm going to try disconnecting that to see if it helps. One noteworthy thing is that these problems are new, whereas the Belkin hub and the Memorex SD card reader have been attached to my MBP for a long time.

10.5.2 - Frozen Grey Boot Screen with Powered USB Hub -

Hey guys I upgraded to 10.5.2 and after I did, I found my powered USB hub was causing a hanging grey screen when I turn the power on. Anyway does anyone know how to make it not lock up on a grey screen? If I unplug the hub it boots, but until I do it is an endless hanging grey screen. If it is a bug can you guys please fix because I find it really annoying to have to unplug and replug my hub every time I boot.

Generic 7 port hub
Ipod, USB Mic, and Mighty Mouse plugged into the hub.

Update: IT only happens when I plug my iPod into the hub that is plugged into my iMac. If I plug my iPod into the Macs USB directly it boots fine. Kinda a crappy bug or maybe a setting I need to change to be able to keep my iPod plugged into my powered usb hub when I boot so it doesn't hang.

MSI K8N Diamond - Boot problems with USB devices attached.

Hi There.
I have been seeking the forums, but havent found the answer to my problem yet.
This is how it goes with ANY USB devices attached to either of the four USB ports on the Motherboard.
When i turn on my system, it hangs in the POST right after displaying the BIOS version (Which I have updated to 1.6) - I cant use my Keyboard to get to the BIOS setup.
Without USB devices attached...
The system boots without problems. And in Windows XP SP2 i can insert my keyboard, mouse etc. and everything works great - both USB 1.1 & 2.0 devices.
I have disabled the KB/USB.. in BIOS and I have disabled the "Boot on other device" option as well.
As I have found on this forum, a lot of people have problems with USB Front panel and D-Bracket (USB ports) connectors causing the system to hang - But my D-Bracket (USB connectors) and my front USB port is at this time DISCONNECTED - so this cannot be the problem.
The D-Bracket shows the "Bios Sign On" information - and stops at that point
Am I having a malfunctioning Motherboard here, or are there any solutions to this problem?
Please help me as I am desperate to have my system work properly.
Regards
Stieper

Well I have read about that somewhere in here, but my problem is NOT with an USB hub, but with any USB device attached to the motherboard's USB slots. It is driving me nuts to be honest!! I think it might be time for RMA
What do you say guys - is my Motherboard ready for RMA, or do I have to try something specific berfore sending it to the retailer??

Problems with the USB Ports

Hi there,
I writing this because I'm having some really big problems with my USB ports.
A few days ago I plugged in an USB-Hub that was quite cheap. Suddenly a window popped up saying that a USB device was deactivated because it "needed" to much power. Since this happening, two of those windows keep popping up everytime I boot the MacBook. I called Apple and got some help: I had to delete some .plist files and clear some caches. The man who helped was able to find the error and deactivate the notification, he also told me to make a PRAM- and a SMC-reset. The man said that it's just a software problem and that I have to reinstall the system if we don't find a solution. So, one day later I reinstalled the system (Lion) and not only didn't it help, the two notification windows were popping up again...everytime I booted the Mac. So I decided to formate the whole hard drive and install Snow Leopard -> still the problem with the USB ports. After that I installed Lion -> still the problem with the USB ports. I even tried to extract the .kext files that are important for the USB functionality from an earlier Combo Update, but it didn't help either. The point is, that the Mac doesn't recognize my external hard drive or any of my iDevices. Sometimes it recognizes USB sticks, but only after 20 seconds. The data transfer on both USB ports is also very slow. If I'm lucky and Mac recognizes one of my USB sticks, it takes like an hour for 1GB to be transfered on the USB stick or from the USB sticks to the Mac.
I really don't know what to do and need help, especially because my backup data is on my external hard drive which I can't access because of this problem.
I really hope that someone can help me, I'm very thankful for every answer that could help me!
PS: Sorry for my bad English, I hope that everyone understands what I mean, please tell me if you don't get what I'm trying to explain in the text above.
Sincerely,
iLoud
[UPDATE] I downloaded "USB Prober" and copied the Output file, maybe it helps:

Can i connect to a 'belkin USB Hub' so i can print and save images direct from my ipad 2..

I have just bought a 'Belkin USB Hub' so that i can have my printer and external hard drive in a home office rather than carting them around the house or having to sit in my back room when i want to print from my mac lap top, works fine , but my question is, is it possible to connect my ipad 2 to the hub so i can edit and print directly from that rather than having to re-sync to my laptop.

The only solution to enable printing with the iPad is via WiFi or by using one of the HP AirPrint compatible printers.

If you don't own of these printers you will need a third party app that will allow you to print. Print n Share, Print Central, and others are available in the App Store. Some of these apps will work only if your computer is turned on and may need a helper app for the computer as well. if you have a Mac you can use Printopia. The computer must be on for this app as well. Print Magic has been mentioned on this site a few times. Google or check the App Store.

Airport Extreme, Belkin USB Hub, and external hard drive

I'm having a serious meltdown. I've been at this all day long and I've reviewed SEVERAL, if not all, discussion threads. I've seen my question many times on many threads, but yet to find a solution!
Just got the hub, and I tried today to connect the Belkin USB hub so I could get my external hard drive accessible from my Mac. My external drive worked fine on my PC. I recently moved to Mac.
Printer works with no issue at all, but my external drive does not even list in either the Disk Utility or System Profiler. It just doesn't get recognized. I've tried EVERYTHING...switching ports, connecting directly to my Macbook, restarting, etc., etc., etc. NOTHING.
Anyone have any insight to this? I'm ready to throw in the towel.

Ok I'll try that! Uh oh...now I can't even see the external drive on my PC! I also spent some time looking at the manufacturer's website to see if there's any software I may have downloaded before using the hard drive, but the website is not helpful in that capacity (www.cavalrystorage.com). I don't remember having software when I first started using it. Furthermore, I just looked at paperwork I received when I got the drive back in Nov.06 and it says not to use "the CD if you have Windows", (to install a driver, perhaps?) which of course, I did. But now I can't find what disc I may have gotten with the drive. It also had no specific instructions for a Mac. Although the external drive has wonderful reviews, and says you can use it with a PC or Mac. I hope this helps. I certainly appreciate your help!
I'm starting to think something has gone awry with the external hard drive? I've tried connecting through the hub (my printer works at least!), direct to AirPort, and direct to laptop and nothing.

Printing issues via a Belkin USB hub to a Samsung ML-2240

Hello All,
I am trying to help a friend of mine setup wireless printing from her Macbook. Unfortunately I don’t know very much about Macs and OSX but I am a quick learner
The setup:
Virgin Media Cable Modem -> connected (RJ45) to a Wireless Linksys Cable Modem -> connected (RJ45) to a Belkin USB Hub.
From the USB hub I have two printers connected:
1 x HP Deskjet
1 x Samsung ML-2240 Laserjet
Both these printers install to the Macbook perfectly as default USB devices (wirelessly) via the USB Hub. They also appear correctly in the Belkin USB Hub software console.
The HP printer works perfectly every time it is used, no issues whatsoever. The Samsung printer prints ok the first time but the print jobs do not disappear from the print queue on the Macbook, the print job doesn’t appear to complete even though it has actually printed without any issue.
The problem this causes is that after the first print job has been printed it is not possible to print again. Even if I delete the print job from the queue manually I cannot still not print a second time. The only way I can get the printer to print again is to unplug and then plug back in the USB cable that is connected to the USB Hub. When I unplug the cable the print job disappears from the queue on the Macbook. I can then reconnect the USB cable and connect to the printer and it will print again.
I have made sure that I have the latest firmware on the Macbook which is running 10.5.* OSX. I have also installed the latest Firmware and Drivers on the Samsung Printer and the USB Hub.
Is there a different way to setup the print queue that you think may help? Any ideas would be greatly appreciated. I spent 5 hours on this yesterday and it still isn’t working
Thanks
M

Further info:
- it appears that the firmware version is 5.7 on this AirPort Extreme
- when I plug in my other printer (Samsung ML-1710), it appears in the list of USB printers in AirPort Utility.
- unfortunately, the ML-1710 is no longer supported in Snow Leopard
- under Printer Setup, Driver, I selected Generic PCL Laser Printer for the ML-1710 as a test - the print queue opened, my printer did its "about to print sound", the print queue told me the job had printed, but nothing came out (yes there was paper )
- found the entry below (from Neptune78 on http://discussions.apple.com/thread.jspa?messageID=10067336&#10067336) re. driver for ML-1710, followed steps successfully until the final printing part when the printer stalls and pauses @ 10% printing stage
Any help appreciated
+Re: It's desperate!! - can't use my Samsung laser+
+Posted: 30-Aug-2009 2:13 PM in response to: ChuckInNJ +
+I got my ML-1710 working today on Snow Leopard. Here's what I did:+
+1. Go to System Preferences -> Print & Fax -> delete printer from the list.+

+You should now be good to go.+

Using with a USB Hub

Hi. Right now I have an old iMac, and I use a USB hub (I have way too many USB devices that I like to have connected at once). If I were to switch to a Macbook along with one of the new 24" LED displays, would I still be able to connect the USB hub to the back of the display, or should I not do this since the display technically functions as a USB hub itself?

USB hubs can be used with other USB hubs as long as the hub they plug into has power, such as the display hubs.

Poll: Do you have cold boot problem with SB X-FI Fatal1t

Hi guys:
I have post a thread regarding the cold boot problem with SB X-FI Fatalty and OCZ GameXStream 600W SLI power supply combination. Apparently, no one has answer to that . In addition, I have recently RMA'd my psu and received a brand-new unit. The same problem still exists. If the problem is really with the power supply, doesn't matter what kind of the setup I have, I should still have the cold-boot problem. However, it doesn't seem like that. Doesn't matter what kind of cards I put on the motherboard, as long as the SB X-FI Fatalty card is there, there is cold boot problem (even with the setup of cpu, mother, ram, and the sound card only, WITHOUT video card and harddri've). And for other different setup without the SB X-FI Fatalty card, there is no cold boot. The cpu and memory are running at stock speed.
My post regarding the cold boot issue:
http://forums.creative.com/creativelabs/board/message?board.id=soundblaster&message.id=79753
There is one user on the forum saying he has the same problem. Therefore, I think it might be the imcompatibility between the X-FI Fatalty and OCZ GameXStream PSU.
I would like to know how many people that has the same problem that I am having. So I can possibly narrow down the problem and contact OCZ tech support or creative tech support with more information. It would also be benefitical to those who have the same problem as I do.
Please post your system setup as well in the thread.
Greatly appreciate your opinions. Message Edited by White_Hair on 2-02-200604:58 AM

I would venture to say that it isn't your powersupply, but more likely the X-Fi. I had troubles with my system, until I pulled out my X-Fi and replaced it with a non Creative Labs sound card. One of my troubles, which I incorrectly blamed on my powersupply was the ASUS A8R-MVP motherboard I had and the X-Fi XtremeMusic card, was after gaming for 4 hours, was the?sudden reboot of my system. Powersupply before, was an Antec TrueControl 2 550watt PSU. As it stands right now, I no longer have the parts mentioned and have a decent 700watt powersupply in my system, along with an ABIT AT8 32X motherboard. As you have probably seen there are a lot of problems with the X-Fi soundcards, and I in my right mind can't blame the motherboard, powersupply, motherboard chipset, ram, or any other component in ones system, if one is having trouble other than the X-Fi itself. I'll be honest, there is something quite frankly wrong with the X-Fi, and exactly what that is, I'll probably never know like most people.

K8N NEO4 Platinum cold boot problem with 165 opteron?

I have this board and have a cold boot problem with my opteron. Is there anything I can do to fix this? Its starting to get very anooying.
K8N NEO4 Platinum
165 opty dual core
2X1GB Ballistix PC4000
160GB sata2
7800GTX
X-Fi platinum
600 watt seasonic PSU

Well I am running them at the rated speed of 250 and the rated timings of 3-4-4-10 on the rated 2.8 volts. Ballistix have been known to die quickly when you throw to many volts at them for some reason. I dont get the cold boot problem with the OCZ. Once I finally get it to boot with the Ballistix it works just fine but the next morning I play hell to get it to boot again. I dont even get the main screen to let me get into bios. It just stays black. I have done all kinds of stress testing and ran memtest with no problems. I am really at a loss here.

Problem with SB1240 USB sound card

I'm pulling hair here! I've just bought a SB240. Windows (XP Pro, SP3) detected it and I can select it fine for listening. But when I open Sound and Audio Device Properties and select Sound Recording/Volume, I see the Capture panel with the three inputs, but all the controls are greyed out and immovable. I also use the application "Total Recorder" by High Criteria, in which I can select the SB240 device but the only input line it sees is SPDIF Interface.
I'm stumped. Can anyone help?
John?

&Re: Problem with SB240 USB sound card
Thank you. I did a complete uninstall, including the device itself (from Device Manager) as well as all drivers and any SB related software. As recommended by Creative, I had previously installed the driver software from the supplied CD and that seems to have been the problem.
I let Windows re-detect the SB, but? got a "problem ... device may not work correctly.." during the detection, so I was not hopeful (this had not happened the first time I installed the device).
Nevertheless it now does work fully and is properly configured in "Total Recorder" too.
So I would suggest not using the supplied drivers and software - at least not in WinXP. But it's not very confidence inspiring.

Problems with wireless usb adapter on MSI K8NGM-V

Hi!
I have a 3Com (3crusb20075) wireless usb adapter, and a MSI K8NGM-V Mainboard. Very often the usb disconnects from the network and i have to reinsert it to work again. A friend of mine have the exact same adapter and that one fails too. He uses mine without problems. I therefore belive that this is a problem with the usb ports on my mainboard. Have anyone heard of anything like this? I wanted to try to update my bios but i don't have a floppy so msi live update wouldnt let me, and i could find the bios files on the msi webpage so i cant burn them on a bootable cd. Help please
(I trying turning of power save mode on the usb adapter, without any luck. Tested it in linux. Same result)
Alex

The ability to access the network, but not the Internet, typically indicates that the computer is not able to either find or negotiate with the DNS servers. The proper DNS servers would be provided by your ISP using DHCP. In turn, the AirPort would use DHCP to provide these to both the wired & wireless computers connected to it.
Please try the following:
For each PC that is unable to access the Internet, temporarily include the following OpenDNS servers:
o Primary: 208.67.222.222
o Secondary: 208.67.220.220
You would enter these in the network TCP/IP settings for the respective PC's wireless network adapters. You may need to restart the computer in order for these DNS settings to "stick." After restarting, can you access the Internet with either or both of them?

Problem with detecting USB devices.. something abt ehci-hcd??

Hi All,
I have a DELL E6410 laptop. I have a problem with connecting USB devices.
Whenever a power event (such as connecting/disconnecting of AC adaptor) happens, my laptop stops detecting any USB devices and any changes that happen on the USB ports. That is, say an external mouse is connected to the laptop, the mouse stops functioning, and if I connect a mouse/USB_stick or any such thing to the computer, the device is not detected.
dmesg output show that any connecting/disconnecting events are not detected by the computer. lsusb output too shows the same thing.
To solve the problem, I need to rmmod the module ehci-hcd and modprobe it back. That is, I have to run the commands rmmod ehci-hcd followed by modprobe ehci-hcd. Then, this problem goes away until the next power event happens.
This event does not happen all the time, but it happens very regularly.
Here are the kernel and laptop specs..

After this the the mouse goes dead (the light on the mouse also goes off).
If I disconnect the mouse at this stage, there is no change in kernel.log. If I the mouse back too, there is no change in kernel.log.
Now, when I turn the AC adaptor on, this is the output on kernel.log

At this point, the mouse comes back to life (its light begins to glow) and I can move the mouse pointer on the screen.
The output of the grep command that rwd gave is too big (16000 lines) to be pasted here..
Thanks,

USB "Low Power Notice" when booting up my G5 with a Belkin USB hub attached

I have a Belkin USB 2.0 hub (FSU237 Rev3) with an external ac adapter.
Everytime I reboot my G5 (running OS 10.4.6), this window pops up:
"USB Low Power Notice
The USB device cannot operate because it needs more power than is available.
To correct this problem you can:
1) Plug the device into an electrical outlet if it has a power cord.
2) Unplug the device and plug it into another USB port on your computer or other device that is plugged into a power cord."
I have tried the hub plugged into the USB jacks in the back of my G5 as well as the front one. It doesn't work. None of the items plugged into the hub show up on the desktop.
I have tried the items I have plugged into the hub (my shuffle and my treo phone with sync cable) by plugging them directly into my G5 (all ports) and they work fine. And I used this hub for months on my PC with no problems.
What could be going on?
PowerMac G5 Quad Mac OS X (10.4.6)

You may want to check System Profiler's USB section to see if the hub even shows up in there (you may have to refresh the list if you try different ports).
I bought one of these hubs for my Quad and it didn't show up at all in System Profiler. Exchanged it for a new one and everything was OK.

Airport Extreme, with Belkin usb 7 Port powered hub, with printer & 2 HD's

I have the Belkin usb 7 Port hub going into the Airport Extreme, my Macbook Pro sees the printer and prints fine, but doesn't see the 2 western digital mini hard drives My AE still has a green light. Is there something else I have to do? Thanks, Schooner

Hi Schooner17-
Are the drives bus-powered?
If so, do they work with the hub on a Mac? Do the drives work 1 at a time?
That hub might not supply enough juice to power both drives.
