是否可以检测 iPhone 上的非 MFI 配件？

我意识到 iPhone 上不可能实际使用任何未经 MFI 认证的外部配件。有什么方法可以简单地检测连接吗？我想做的就是从 USB 驱动器获取序列号。

到目前为止，我已经尝试了以下

- (void)pollAccessories {
    statusText.text = [NSString stringWithFormat:@"%@%@", statusText.text, @"\r\nPolling Accessories..."];

    NSArray *accessories = [[EAAccessoryManager sharedAccessoryManager] connectedAccessories];

    for (EAAccessory *obj in accessories){
        statusText.text = [NSString stringWithFormat:@"%@%@", statusText.text, @"\r\nLocated Accessory"];
        if(obj.connected)
            statusText.text = [NSString stringWithFormat:@"%@%@", statusText.text, @"\r\nConnected\r\n"];
    }
}

似乎在模拟器中工作（我得到了两个“连接”的配件）。在连接到 PC 和 PS3 的手机上运行它，但没有任何乐趣。不幸的是，我手头没有合适的适配器来测试合适的 USB 驱动器。

我设法在 iHome 收音机上测试了我的代码。它确实检测到连接，因此代码正在运行。我订购了 USB 加密狗来查看是否可以检测到拇指驱动器。

I realize it is impossible to actually utilize any external accessories that are not MFI certified with the iPhone. Is there any way to simply detect a connection? All I would like to do is acquire the serial number from a USB drive.

So far I've tried the following

- (void)pollAccessories {
    statusText.text = [NSString stringWithFormat:@"%@%@", statusText.text, @"\r\nPolling Accessories..."];

    NSArray *accessories = [[EAAccessoryManager sharedAccessoryManager] connectedAccessories];

    for (EAAccessory *obj in accessories){
        statusText.text = [NSString stringWithFormat:@"%@%@", statusText.text, @"\r\nLocated Accessory"];
        if(obj.connected)
            statusText.text = [NSString stringWithFormat:@"%@%@", statusText.text, @"\r\nConnected\r\n"];
    }
}

Seems to work in the simulator (I'm getting two accessories that are "connected"). Ran it on my phone connecting to a PC and my PS3 with no joy. Unfortunately I don't have the appropriate dongle on hand to test a proper usb drive.

UPDATE 4/27/11:

I managed to test my code on an iHome radio. It does detect the connection, so the code is working. I've ordered a USB dongle to see if I can detect a thumb drive.
